Question

What happens to the particles in a solid when they are heated?

Answer 1

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
