What happens when you heat solids?

Answer 1

when a solid is heated the particles in it gain energy (heat energy) and vibrate more. The particles bump into each other and pass the energy on. The speed all depends on whether the solid is a conductor of heat or electricity.

Answer 2

The molecules in the material will start to become more energetic and break the bonds that tie them together. This causes the material to expand. Ultimately, the bonds are broken and the material has reached melting point when it becomes a liquid.

There are some materials which do not melt, they sublime and change directly from the solid state to the gaseous (or vapor) state.

Other materials will burn if heated. This happens when the molecules chemically react with the oxygen in the air and convert to new oxides and residues.

Answer 3

1. When a solid is heated the particles vibrate more and they break free of the mold they are in. This makes the solid a liquid. if you continue to heat it, the vibrations will get stronger and the particles will start to evaporate. When all the particles have evaporated, then it would be a gas.

2. Thermal dilatation

3. Modification of all other physical properties (density, electrical conductivity, etc.

4. In some cases, thermal degradation.

Answer 4

First it gets warm and later it gets hot. Depending on the solid it might change shape. At some temperature all solids will change shape or become destroyed.

Answer 5

The solid will turn into a liquid, but if it is heated too much then it will turn into a gas because the molecules will get further away from other molecules.

Answer 6

they melt
