Question

interconversion of matter on the basis of kinetic theory on heating solid
1)particles lose energy
2)particles gain energy
3)intermolecular space decrease
4)intermolecular attraction increase​

Answer 1

2. Particles gain energy.

Hope it helps you...

Answer 2

Answer:

when particles lose energy their intermolecular space decreases and the solid becomes colder and colder.

when particles gain energy their intermolecular space increases and solid the solid becomes hot and changes first to a liquid and then to a gas. It may also change into a gas by sublimation.
