Evaporation is the conversion of water to vapour at a temperature below boiling point.
Water has a 'Vapour Pressure' at any temperature below 100°C at atmospheric pressure. (At the boiling point, water is NOT evaporating, it's Vaporising. Evaporation takes place below the boiling temperature).
The molecules leaving the water as vapour are moved away by any movement of air above the water and therefore cannot return to the water. The Energy required to evaporate the water is called 'Latent Heat' and takes place by removing the necessary heat from the water as 'Sensible Heat' thereby decreasing the water temperature.
This principle is also used by the body on a warm day. The body gets hot, it sweats, the sweat evaporates off the skin and the body cools down.

Evaporation causes cooling effect Explain with examples?
when a liquid evaporates,it gives its latent heat of vaporisation.if no heat is supplied from outside this results in cooling.
How does evaporation causes cooling with examples?
sweating
What is cooling effect?
Cooling Effects is caused by the melt down of mountain glaciers at the north pole when this continue it will cause the earth a climate change.
How is evaporation used for energy transfer?
In order to evaporate, energy has to be added to the system, so there will be energy transfer from the surroundings into the material being evaporated, with the effect of cooling the surroundings.
Is it true that the increased cooling that a wind can cause is called the Coriolis effect?
No. The Coriolis effect is the deflection of wind and ocean currents caused by Earth's rotation. The increased cooling from wind is called wind chill.
Why evaporating of water cause cooling?
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
How evaporation exhibit the cooling effect?
Evaporation needs heat energy. During the process of evaporation heat is absorbed by the other body thereby cooling it
How do you find out the effect of evaporation on skin?
Evaporation causes cooling . The skin cools when evaporation takes place.
Does evaporation cause cooling in the residual liquid?
yes
What conclusion can you make about the effect of the evaporation on cooling?
what is the conclusion of evaporate rate water
Which property of water accounts for the cooling effect of perspiration?
The latent heat of evaporation.
How does carbon dioxide effect the cooling of evaporation?
Carbonation does not evaporate as quickly as water.
Why is cooling always cause evaporation?
Cooling does not cause evaporation. Warming does. This is because as the air warms up, there's more space for water vapor in it. Water evaporates and turns into water vapor to fill this space.
What is evaporation used for?
When you perspire, the sweat evaporates and gives off this cooling effect. There are many examples to show it too.
Why does evaporation have a cooling effect?
In order for liquid to evaporate, potential energy should first be acquired to be able to transform to gas. This energy will be stored as heat. Heat will not cause temperature to increase and this is known as latent heat. Boiling of water puts potential energy into it. Once it boils, the water evaporates into the air and also takes heat from the surroundings. This is what causes the cooling effect of evaporation.
