Required Practical: Investigating Specific Heat Capacity ( AQA GCSE Physics )

Revision note.

Required Practical 1: Investigating Specific Heat Capacity

Aims of the experiment.

• The aim of the experiment is to determine the specific heat capacity of a substance, by linking the amount of energy transferred to the substance with the rise in temperature of the substance
• Independent variable = Time,  t
• Dependent variable = Temperature, θ
• Material of the block
• Current supplied,  I
• Potential difference supplied,  V

Equipment List

• Thermometer = 1 °C
• Stopwatch = 0.01 s
• Voltmeter = 0.1 V
• Ammeter = 0.01 A

Apparatus to investigate the specific heat capacity of the aluminium block

• Start by assembling the apparatus, placing the heater into the top of the block
• Measure the initial temperature of the aluminium block from the thermometer
• Turn on the power supply and start the stopwatch
• Whilst the power supply is on, the heater will heat up the block. Take several periodic measurements, eg. every 1 minute of the voltage and current from the voltmeter and ammeter respectively, calculating an average for each at the end of the experiment up to 10 minutes
• Switch off the power supply, stop the stopwatch and leave the apparatus for about a minute. The temperature will still rise before it cools
• Monitor the thermometer and record the final temperature reached for the block
• An example table of results might look like this:

Analysis of Results

• The thermal energy supplied to the block can be calculated using the equations:
• E = thermal energy, in joules (J)
• Q = Charge, in coulombs (C)
• I = current, in amperes (A)
• V = potential difference, in volts (V)
• t = time, in seconds (s)
• Rearrange to make Q the subject
• Substitute into the Q = It equation
• Rearrange to make E the subject
• The change in thermal energy is defined by the equation:
• Δ E = change in energy, in joules (J)
• m =  mass, in kilograms (kg)
• c =  specific heat capacity, in joules per kilogram per degree Celsius (J/kg °C)
• Δ θ =  change in temperature, in degrees Celsius (°C)
• Rearranging for the specific heat capacity, c :
• To calculate Δθ:
• To calculate Δ E:
• I = average current, in amperes (A)
• V =  average potential difference (V)
• θ f = final time, in seconds (s)
• θ i = initial time, in seconds (s)
• These values are then substituted into the specific heat capacity equation to calculate the specific heat capacity of the aluminium block

Evaluating the Experiment

Systematic Errors:

• Make sure the voltmeter and ammeter are initially set to zero, to avoid zero error

Random Errors:

• This means the measured value of the specific heat capacity is likely to be higher than what it actually is
• To reduce this effect, make sure the block is fully insulated
• This would eliminate errors from the voltmeter, ammeter and the stopwatch
• Make sure the temperature value is read at eye level from the thermometer, to avoid parallax error
• The experiment can also be repeated with a beaker of water of equal mass, the water should heat up slower than the aluminium block

Safety Considerations

• Run any burns immediately under cold running water for at least 5 minutes
• Allow time for all the equipment, including the heater, wire and block to cool before packing away the equipment
• Keep water away from all electrical equipment
• Wear eye protection if using a beaker of hot water

Teacher tip

From my experience of teaching this practical investigation, it is usually done as a teacher demonstration because of the specialist equipment used. Therefore, students find it more difficult to engage with than a hands-on practical, and so can often find it quite confusing. This Required Practical does come up in exams very frequently, so you do need to make the extra effort to understand the equipment, the set-up and how the measurements are taken.

The main idea is that the measurements of current and potential difference allow you to calculate the energy transferred to the metal block, and from there you can use the change in temperature and the energy supplied to calculate the specific heat capacity of the metal.

Determining Specific Heat Capacity Through Experiment

Objectives:

• To understand how to practically determine the specific heat capacity of a substance

Introduction  

A practical for specific heat capacity involves measuring the temperature changes of different materials when they are heated . An investigation involves linking the decrease of one store of one energy store to the increase in thermal energy store. As you would expect, the energy transferrer (work done) will cause a temperature to rise.

As you will have learned on the specific heat capacity page, the temperature rise of a material depends on its specific heat capacity. Materials with a low specific heat capacity (a low capacity to store thermal energy) will have a greater temperature increase than those with a high specific heat capacity.

Apparatus required

• Aluminium block with two holes, one for a thermometer and one for a heater
• 50 W, 12 V heater

• Thermometer
• Beaker (250 cm 3 )

Safety precautions

• The heating element will get very hot, especially if not inside a metal block. Take care not to burn yourself
• Damaged equipment should not be used (e.g. bare wires etc.)
• If you scald yourself with the heater or water then, cool under running cold water immediately for 10 minutes.
• Measure the mass of the aluminium block using the balance, if recorded in grams, this should be converted into kilograms.
• Place the heater and thermometer into the aluminium block

• Measure the  starting temperature of the metal block (you may need to wait for the thermometer to stop changing first).
• Turn the power pack on and up to about 5V, this can be higher for certain heaters (but it will say the maximum on it)
• Record the ammeter and voltmeter readings every 60 seconds in a table like that shown further down this page. These values may vary during the experiment, but they shouldn’t do significantly. Whilst recording the ammeter and voltmeter reading, also record the new temperature of the block at each 60s interval.
• After about 10 minutes turn off the power supply.
• Keep the thermometer in the metal block for a while longer. Record the maximum temperature of the block. The heater will still have some energy after you have turned off the power supply so you want to record any additional temperature rise from this energy.

Examples of results tables you should consider using:

Things to consider before experimenting

• The heating element should fit very snuggly into the metal block, but there may be a small layer of air between the heating element  and the metal block. Add a drop of water before you put the heating element in to improve transfer of energy between the heating element and the metal block.
• Remember to measure the mass of the metal block. These blocks are usually 1kg, but to make sure your calculations are accurate, you should take an accurate mass measurement.
• Make sure you heat the metal block for at least 10 minutes; otherwise you will not be able to draw a graph with a good range of results.
• Don’t forget to use your graph to find the gradient of the line. You will need this and the mass of the block to work out the specific het capacity  of the metal.

Analysing the results

After drawing you line of best and taking your gradient the specific heat capacity can be found by using the following equation:

Exemplar graph and results:

****waiting for a good graph to be drawn from a student ****

• Usually, the value for specific heat capacity found is higher than it should be, this is because more energy is put into the system than that used to heat up the substance. Some energy goes into wasted energy, such as heat loss to the surroundings. To improve the results, an insulation material should be used around the block.
• If you are trying to determine the specific heat capacity of a liquid, then the liquid should be stirred before each measurement to ensure all the water is the same temperature. Additionally, a lid should be used, since heat rises this is one way thermal energy can be lost to the surroundings.

• To Determine Specific Heat Capacity Of A Given Solid By Method Of Mixture

To Determine Specific Heat Capacity of a Given Solid by Method of Mixture

Specific heat capacity is defined as the amount of heat required for one gram of substance at 1℃. To understand how to determine the specific heat capacity of a given solid by the method of mixtures, please read the below article.

To determine the specific heat capacity of a given solid by the method of mixtures.

Materials Required

• A hypsometer
• Calorimeter
• A lid and outer jacket
• Solid in small pieces
• Two half-degree thermometers
• Clamp stand

The calorimeter is a device used to measure the heat flow of a chemical or physical reaction. Calorimetry is the process of measuring this heat. It consists of a metal container to hold water above the combustion chamber and a thermometer to measure the temperature change. Hypsometer is an instrument used to determine the boiling point of water at a given altitude.

• Put thermometers A and B in a beaker containing water and note their reading. Let thermometer A be a standard to find the correction that is to be applied to thermometer B.
• Put the thermometer B into the copper tube of a hypsometer containing the powder of the given solid. Before placing the hypsometer on the burner, add a sufficient amount of water.
• Record the weight of the calorimeter with a stirrer and lid over it.
• Add water (temperature between 5 to 8℃) to the calorimeter at half-length and weigh it again.
• Heat the hypsometer till the temperature of the solid is steady.
• Note the temperature of water in calorimetry. Now slowly stir and add the solid powder from the hypsometer to the calorimeter and record the final temperature of the mixture.
• Remove thermometer A from the calorimeter.
• Note the weight of the calorimeter with the contents and lid.

Observations

Reading of thermometer A = T A = ……… ℃

Reading of thermometer B = T B = ……… ℃

Correction applied in B with respect to A (T A – T B ) = …….. ℃

Mass of calorimeter and stirrer m = …….. g

Water equivalent of calorimeter ω = m × 0.095 = …….. g

Specific heat of copper calorimeter = 0.095 cal/g

Mass of calorimeter + stirrer + lid = m 1 = ……. g

Mass of calorimeter + stirrer + lid + cold water = m 2 = …… g

The steady temperature of hot solid = T s = …….. ℃

Corrected temperature of hot solid T =T s – (T A – T B ) = ……… ℃

The temperature of cold water = t =……… ℃

The temperature of the mixture = Ө =…….. ℃

Mass of calorimeter, stirrer, lid, cold water, and solid = m 3 =…… g

Calculations

Mass of cold water = m 2 – m 1 =…….. g

Mass of hot solid = m 3 – m 2 =…….. g

Rise of the temperature of cold water and calorimeter = Ө – t =………. ℃

Fall in temperature of solid = T – Ө =……… ℃

Heat gain by calorimeter, cold water and stirrer = [ω + ( m 2 – m 1 )(Ө – t)] =……. (a)

Heat lost by solid = (m 3 – m 2 ) × C × (T – Ө) =……. (a)

Here, C is the specific heat of solid to be calculated.

According to the principle of calorimeter, heat lost = heat gained

Specific heat of given solid by the method of the mixture is ………. cal g -1 ℃ -1 .

Precautions

• A sufficient amount of solid powder should be used to cover the tip of the thermometer.
• A sufficient amount of water should be taken in a hypsometer.
• Dropping of solid should be quick and gentle.
• To avoid excess radiation, the calorimeter should be polished from the outside.
• The temperature of cold water should not cross the dew point.

Sources of Error

• There might be heat loss while transferring solid into the calorimeter.
• During conduction, convection, and radiation, there might be heat loss.
• The bulbs of the thermometer might not be completely inside the solid.

Note: To determine the specific heat of a given liquid by the method of mixtures, the liquid is taken in place of cold water to determine the specific heat. Proceed with the same procedure as in the experiment.

Q1. What is the heat?

Ans: Heat is defined as the quality of being hot at high temperatures.

Q2. Define the specific heat of the substance.

Ans: It is defined as the amount of heat energy required to raise the temperature of 1 gram of a substance by 1℃.

Q3. State the principle of calorimetry.

Ans: The principle of calorimetry is heat lost is equal to the heat gained.

Q4. Why is calorimeter made of copper is used in the experiment?

Ans: The specific heat of copper is very low. The absorption and liberation of heat will be less during heat transfer.

Q5. Is heat gained always equal to the heat lost?

Ans: If there is no chemical reaction taking place between the components only then heat loss will be always equal to the heat gain.

What are the precautions in specific heat capacity experiment?

There are several precautions that should be taken in specific heat capacity experiments:

• The sample should be of a known, uniform composition.
• The sample should be of a known, uniform size.
• The sample should be of a known, uniform shape.
• The sample should be clean and dry.
• The sample should be at the same temperature as the calorimeter.
• The calorimeter should be well insulated.
• The calorimeter should be of known heat capacity.
• The surroundings should be at a constant temperature.

David Denton ∙

Some precautions to consider in a specific heat capacity experiment include ensuring that the equipment is calibrated correctly, using an appropriate amount of the substance being tested, maintaining a consistent temperature throughout the experiment, and taking proper safety measures when handling hot objects or substances.

Add your answer:

What is the precaution taken on specific heat capacity experiment?

Some precautions taken during a specific heat capacity experiment include ensuring the apparatus is properly calibrated, using consistent and accurate measurements, minimizing heat loss to the surroundings, and maintaining a controlled environment to reduce external influences on the results. These precautions help ensure the accuracy and reliability of the data collected during the experiment.

What are precaution in specific heat capacity experiment?

Some precautions to consider in a specific heat capacity experiment include ensuring proper insulation to minimize heat loss, using accurate measuring instruments to determine mass and temperature changes, and conducting the experiment in a controlled environment to avoid external influences on the results. Additionally, it's important to handle hot objects with care and follow appropriate safety protocols when working with heat sources.

To determine the specific heat capacity of a solid conclusion?

To determine the specific heat capacity of a solid, conduct an experiment where you measure the temperature change of a known mass of the solid when a known amount of heat is added or removed. By calculating the specific heat capacity using the formula Q = mcΔT (where Q is the heat energy, m is the mass, c is the specific heat capacity, and ΔT is the temperature change), you can determine the specific heat capacity of the solid. Repeat the experiment multiple times to ensure accuracy and reliability in your conclusion.

Why does the temperature of the metal fall from its maximum after a while in a specific heat capacity of metals experiment?

The temperature of the metal falls from its maximum during a specific heat capacity experiment because the metal is losing heat to its surroundings through conduction and radiation. This heat loss causes the temperature to decrease over time until it reaches equilibrium with the surrounding environment.

How do you reduce the errors in specific heat capacity experiment?

To reduce errors in a specific heat capacity experiment, ensure proper calibration of equipment, accurately measure mass and temperature, minimize heat loss through insulation, and repeat measurements to calculate an average. Additionally, use a consistent method and ensure the substance is uniform to improve accuracy.

The Precautions: Sufficient solid power should be taken to cover the tip of the thermometer properly. Sufficient water should be taken in the hypsometer. The solid should be dropped quickly and gently. The calorimeters generally should be polished from outside to avoid excessive radiation losses. What are the precautions and conditions for a calorimetric experiment? Precautions Do not stir the liquid in the calorimeter vigorously because vigorous stirring does cause some increase in temperature. The space between the calorimeter and the wooden box should be filled with cotton to avoid heat loss. Which three factors affect specific heat capacity? This quantity is known as the specific heat capacity (or simply, the specific heat), which is the heat capacity per unit mass of a material. Experiments show that the transferred heat depends on three factors: (1) The change in temperature, (2) the mass of the system, and (3) the substance and phase of the substance. Why must the sample be poured safely but quickly into the calorimeter? The sample must be poured safely but quickly into the calorimeter, so that a minimal amount of heat is lost to the surrounding air. If water from the beaker entered the calorimeter in would add heat that is unrelated to the sample and alter the calculated mass of water. What are the materials required in an experiment to find specific heat of solid? Material Required: Calorimeter, Thermometer, Stirrer, water, steam heater, wooden box and solid whose ‘S’ to be found. Procedure: Measure the mass of calorimeter with stirrer. Knowing the specific heats of calorimeter and water, we can calculate the specific heat of the solid (lead shots). What is the conclusion of specific heat capacity? Conclusion: The specific heat capacity of Alumium is 900J/Kg/K and the specific heat capacity of Lead is 1300J/Kg/K. This is as I predicted. This means that it takes more energy to change the temperature of lead than of Aluminium. What are the safety precautions when handling bomb calorimeter? Submerge the bomb in the calorimeter bucket, avoid tilting the bomb. Make sure that there are no persistent gas bubbles escaping from the bomb seal. If you see gas escaping, DO NOT CONTINUE. Which of the following are precautions to be followed while conducting the Newtons law of cooling experiment? Precautions. Stir the water/oil to allow uniform cooling. Room temperature should remain constant. Avoid any heal source near the experiment site so that room temperature remains constant. How does temperature affect specific heat capacity? Then as temperature increases more of the energy levels become excited & the internal energy rises rapidly and so does the slope of U vs T and so heat capacity increases. How does specific heat depend on temperature? At low temperatures, collisions do not provide enough energy to get out of the ground states for rotation or vibration. The average energy increases only from translation. As the substance heats up, the average kinetic energy of the molecules increases. It then contributes to the specific heat. What would be some errors when measuring the specific heat of a metal? One of the common sources of error in the determination of the specific heat capacity of a metal is that some heat is lost during the transfer of a metal from the boiling water to the calorimeter.
