Energy must be put into whatever is being evaporated (to turn int from liquid to gas).
An example is when one sweats, the body cools as the sweat evaporates, because the energy for the sweat (water) to evaporate is taken from the body/skin.

∙ 12y agoif you have sweat on your body, some of the water is cold and some is warm so it will have an effect on your body temperature. For example if you lick your finger and blow on it, it will feel cold. this is becuase of the heat in your body

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.
Why evaporating of water cause cooling?
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
What conclusion can you make about the effect of the evaporation on cooling?
what is the conclusion of evaporate rate water
How does carbon dioxide effect the cooling of evaporation?
Carbonation does not evaporate as quickly as water.
Which property of water accounts for the cooling effect of perspiration?
The latent heat of evaporation.
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.
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.
Cooling effect of alcohol on the skin is the result of?
it is the simple principle of evaporation. The same effect can be acheived with any liquid that can evaporate at or around body temperature. Alcohol has a low evaporation point, when you apply it to your skin it draws heat energy from your skin and evaporates off, this process has a cooling effect because it is drawing heat energy from your body.
Why you consider evaporation is heat-absorbing process has a cooling effect?
the hot air is being lifted or released into the air
Is evaporation endothermic or endothermic?
Always endothermic. Liquids absorb heat from the surroundings through evaporation, and keeps continuing this to regain lost energy. This produces a cooling effect in the surroundings.
How does an electric fan give cooling effect on a hot day?
The cooling effect is from evaporation mainly. The fan moves an increased amount of air and speeds the evaporation from the skin or other moist surface. A fan blowing on a dry surface will have no cooling effect more than the average temperature of the air. Secondly, another cooling effect happens if the outer temperature is under 36C degree by pushing the hot (36C degree hot) air away from the surface over the surface of body and exchange it by a lower temperature one.
