When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining energy.
Generally, melting is the process of turning from a solid to a liquid. It entails gaining 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
Water molecules gain energy in order to vaporize. That additional energy is needed in order for the water molecules to overcome the attraction that they have for the other water molecules in the liquid that they are part of. In the gas phase, water molecules move independently of each other and are not connected as they are in the liquid state.
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
A material must gain energy both before and during melting.
As they lose energy, atoms or molecules will become more ordered.

When water gains energy the water molecules turn into vapor also known as Evaporation.

Lose
Most substances lose or gain energy when their temperature changes.
The enrgy is always lost or gained in only the definite amount that is called as discrete or packet energy.
They lose energy.
An ion.
When condensation occurs, it is a gain thermal energy.
