Question

ok so when a liquid is freezed it turns into a solid, but when it melts does that give of heat or energy?

Answer 1

It takes energy to go from a solid to a liquid. You must add energy. Melting takes added heat.

To go the other direction, from a liquid to a solid, energy is given up. Freezing gives  heat back to the environment.

Answer 2

did we need to know this for somehting ash?

Answer 3

When something melts, it by definition rises in temperature.  So it uses or absorbs heat (energy) rather than gives it off.

Answer 4

Define "freezed" so I can answer your q.
