Answer 2

Fill it :

1. Matter is made up of small particles .

2.The forces of attraction between the particles are maximum in solids, intermediate in liquid and minimum in gases.

3. Sublimation is the change of gaseous state.

4. Evaporation causes cooling .

5. Latent heat of fusion is the amount of heat energy required to change 1 kg of solid into liquid at its melting point .

6. Solid, liquid and gas are the three states of matter.

7. The smell of perfume gradually spreads across a room due to diffusion .

8. Rapid evaporation depends on the surface area exposed to atmosphere.

9. As the temperature of a system increases, the pressure of the gases decreases .

10. As the volume of a specific amount of gas decreases, it’s pressure increases .

11. As the temperature of a gas decreases, Its volume remains constant .

12. Gas molecules at higher temperatures have more space or kinetic energy then at cooling temperatures.

More Info :

• The particles of matter are very small and have space between them.
• The temperature at which solid melts and convert into liquid is called melting point.
