They vibrate. And if heated enough, most connections will be broken and the object will be melted.
The bonds between solid particles are weakened.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
When a solid is heated its particles melts and change into liquid
When a solid is heated its particles melts and change into liquid
When a solid is heated its particles melts and change into liquid
if they are heated then they turn to a liquid, if that are a soled well they are hard like ice
Thermal expansion occured.
The particles in a solid, move very little. But when it is heated, the particles expand because the heat moves the particles around more, making them need more space to move, therefore expanding the solid. =)

When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.

This physical change is called melting.
