What happens when you heat a solid? Heating a substance Increases its thermal energy.
When the partides in a solid have more thermal energy, they vibrate more quickly, and the
temperature of the substance goes up. Once the substance reaches a certain temperature,
called its melting point, the substance can begin to change state.
As more thermal energy is added to the substance, its partides gain enough thermal energy
to move around more freely. The partides remain close together, but they are able to slide
past one another. When all of the particles have broken out of their fixed positions, the
substance has changed state.
