Answer 2

Explanation:

1. Solids have infinite number of free surface.
2. The molecules of a gas generally move in many direction
3. The various state of matter can be interchanged into one another by altering the conditions of temperature and pressure
4. The process due to which liquid changes into gaseous state by liberating heat energy at certain temperature is called evaporation.
5. By fractional distillation (cryogenic distillation) of air, we can separate oxygen and nitrogen gases.
