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.
When matter melts (changes from a solid to a liquid state), its molecules move faster, meaning they are gaining 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
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
When steam condenses to form water, it releases energy in the form of heat to the surroundings. This energy is needed to break the intermolecular forces that hold the water molecules together as steam.
Freezing typically represents a loss of energy. When a substance freezes, its molecules lose kinetic energy and slow down, leading to the formation of a solid structure. This process releases energy in the form of heat.
When water gains energy the water molecules turn into vapor also known as Evaporation.
For the runner to cool
The process through which bodies of water lose water molecules is called evaporation. During evaporation, liquid water molecules gain energy, typically from heat, and transition into vapor, entering the atmosphere. This process is a crucial part of the water cycle, contributing to weather patterns and climate.
During evaporation, a substance gains energy from its surroundings to break the intermolecular bonds and escape as a gas. This results in a cooling effect on the surroundings as energy is absorbed by the substance.

For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.

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.
