NCERT Solutions of Class 9 Science Book Chapter brief
Chapter 1: Matter in Our Surrounding
The Class 9 science textbooks start with the chapter “Matter In Our Surrounding”. Everything that we see around us is made up of material which is called a matter. These things occupy space and have mass. Earlier, Indian philosopher had classified matter into 5 basic elements, Panch Tatva – air, water, earth, sky and fire. Now, modern scientists have evolved 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.
Chapter 2: Is Matter Around Us Pure – Term I
