Evaporation is an endothermic process.
when water evaporates it absorbs heat energy and cools the surrounding air
The energy transfer in boiling water occurs at the surface of the water where heat is transferred from the heat source to the water molecules. As the water absorbs enough heat energy, the molecules begin to move faster and eventually reach a point where they turn into steam and evaporate.
Water absorbs heat from its surroundings - causing it to evaporate... taking the heat with it.
In order to evaporate, water needs energy in the form of heat to break its intermolecular bonds and transition from a liquid to a gas. This process occurs when water absorbs enough thermal energy from its surroundings to overcome the forces that hold its molecules together.
Heat energy.
The main source of heat that makes water on the earth evaporate is the thermal energy from Sun.
Heat energy makes water evaporate and rise into the air as water vapor.
Heat must be added to a liquid in order for it to evaporate into gas. The heat energy used to do this moves into the liquid, and in the case of your body the sweat. When the sweat evaporates it takes away the heat energy used by it to evaporate, thus removing this heat energy from the skin, causing a cooling effect.
Clear water evaporates first because it absorbs more heat from the sun. Dark water typically absorbs more heat, but in this case, the clear water absorbs more because it doesn't have the dark color to reflect sunlight.
It is called vaporization, and it happens because the water vapor is taking away some of the heat in the form of energy, and so the surface has less heat energy.
The sweat absorbs the heat from your skin in order to evaporate.
