Elianna Fischer · Answer 1

Solid particle matters are more closely packed with each other and when they get energy in the form of heat, they try to move away from each other, expand and swell. That is why solid expand on heating.

Ray · Answer 2

The reason is because when molecules get hot they move faster and they need more room to move.
