Answer:

In a solid the strong attractions between the particles hold them tightly packed together. Even though they are vibrating this is not enough to disrupt the structure. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... The energy is provided when the solid is heated up

Answer:

Solids expand on heating... Bcoz their intermolecular attractions decrease.... And spaces bw their atoms increase
