Question

With reference to inter-conversion of matter – on the basis of kinetic theory – explain in brief the conversion of A liquid into vapour [or gas] With special reference to inter-particle space & interparticle attraction at the different stages of conversion.

Answer 1

A liquid into vapour [or gas] :

1. The heat energy absorbed -stored as potential energy.
2. Inter-particle space-increases.
3. Inter-particle attraction-decreases (almost negligible).
4. Collision-increase and particles push apart to become free and escape the gas.
   Liquid changes into vapours.
