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

उत्तर
A solid into a liquid: Kinetic energy increases
- Heat energy is absorbed by the molecules and stored in the form of potential energy.
- Inter-particle space-increases.
- Inter-particle attraction-decreases.
- Collision-increases and push apart.
Solid changes into a liquid.
