प्रश्न
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.
उत्तर
A liquid into vapour [or gas] :
- The heat energy absorbed -stored as potential energy.
- Inter-particle space-increases.
- Inter-particle attraction-decreases (almost negligible).
- Collision-increase and particles push apart to become free and escape the gas.
Liquid changes into vapours.
