Q. What happens when Solids are heated? ​

Answer 1

When a solid is heated the particles gain energy and start to vibrate faster and faster. ... At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

Answer 2

Answer:

When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
