In this Mission Mid-Terms series, your favourite BYJU’S teacher, Kriti Ma’am, discusses some important concepts in your class 9 Science chapter 1, Matter in Our Surroundings.
Some of the topics covered in this chapter are as follows:
- Physical Nature of Matter
- Characteristics of Particles of Matter
- States of Matter
- Evaporation
The matter is made up of small particles. The matter around us exists in three states- solid, liquid and gas. Evaporation is a surface occurrence. Particles from the surface gain enough energy to overcome the liquid's attraction forces and transition to the vapour state. Join this class to learn more about Matter in Our Surroundings.
