The molecules are moving (just) fast enough to break the bonds that was holding the substance into a crystalline (or quasicyrstalline) form.
it decreases.
When a substance melts, it changes from a solid state to a liquid state. This transition occurs when the substance absorbs enough heat energy to break free from its fixed, ordered solid structure and allows its molecules to move freely in a less structured liquid state.
As a substance melts, the molecules of the formerly-solid substance becomes less structured and drifts further apart.
it melts
During melting, the particles in a substance gain enough energy to overcome the forces holding them in a fixed position in the solid state. As a result, the particles start to move more freely, causing the solid substance to transition into a liquid state.
When sugar melts it turns into a brown sticky substance we know as caramel.

A substance changes from a solid to a liquid at the substance's melting point. This is a different temperature for every substance. For example, water (ice) melts at 0oC, whereas gold melts at 1,064oC.

Lava.
Mercury melts at approximately -38.9 degrees Celsius.
THE SUN!!!! ,of course
decreasing the temperature
