Question

4) on heating solide
to a small extent​

Answer 1

Answer:

When a solid is heated, its atoms vibrate faster about their fixed points. The relative increase in the size of solids when heated is therefore small. ... Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.

Answer 2

Hey there friend, I'm here to help you so here's your answer:

When a solid is heated, the molecules that make up the solid begin to vibrate. This causes them to take up more space, and the solid matter expands. If the heat continues to build, it may provide enough energy for the particles to break free from their strong attraction to one another, causing the solid to melt.
