Generally, melting is the process of turning from a solid to a liquid. It entails gaining energy.
The substance that melts must absorb energy from its surroundings.
melting gains heat energy
It takes energy to make something melt.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
They lose energy.
Vaporatization gains energy because it is the opposite of evaporation and evaporation loses energy. Here are some other things that, like vaporation, gain energy: -melting ... ... ... ... wait one minute, let me think again... oh ya now i remember... -nothing else :D
lose energy: gravity, otherwise see neuton's laws

A material must gain energy both before and during melting.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.

Most substances lose or gain energy when their temperature changes.
They lose energy.

When condensation occurs, it is a gain thermal energy.

A solid melts when it gains enough thermal energy.
You have to put energy IN to keep it boiling, so the water molecules gain energy (from the heating source): the answer is 'GAIN energy' and NOT (as wrongly stated before) 'LOSE' it.water only looses energy when it turns into a solid.and adds energy when turning into a gas
