NCERT Solutions of Class 9 Science Book Chapter Brief

Chapter 1: matter in our surrounding.

The Class 9 science textbook starts with the chapter “Matter in Our Surroundings”. Everything that we see around us is made up of material which is called matter. These things occupy space and have mass. Earlier, Indian philosophers had classified matter into 5 basic elements called Panch Tatva – air, water, earth, sky and fire. Now, modern scientists have come up with 2 types of classification, i.e., based on physical property and chemical nature. In this chapter, students will learn about the physical properties of matter .

The matter is made up of particles and these particulars are very small. The particles of matter have space between them, they are continuously moving and attract each other. The matter around us exists in 3 different states – solids, liquids and gases. These states of matter arise due to variation in the characteristic of the particles of matter. All the 3 states of matters have been explained in-depth with the help of activities. Further, the textbook explains that the state of matter is inter-convertible. The state of matter can be changed by changing temperature or pressure. The phenomenon of change of a liquid into vapour at any temperature below its boiling point is called evaporation. The rate of evaporation depends upon the surface area exposed to the atmosphere, the temperature, the humidity and the wind speed. Evaporation also causes cooling.

Topics Covered in Class 9 Science Chapter 1 Matter in Our Surrounding :

Definition of matter; solid, liquid and gas; characteristics – shape, volume, density; change of state –  melting (absorption of heat), freezing, evaporation (cooling by evaporation), condensation, sublimation.
