In evaporation a substance changes its state from liquid to gas, such as water changing to steam. For this process to occur energy in the form of heat is required (endothermic process) which has to be taken from some source (surroundings). So the source, which loses heat apparently becomes 'cooler'. Hence it can be said that evaporation causes cooling.

Does evaporation cause cooling in the residual liquid?
yes
How does evaporation work in the water cycle?
when liquid evaporate, it turns into a gas. The evaporation process causes cooling on the surface of where the liqiud originated
Which property of water accounts for the cooling effect of perspiration?
The latent heat of evaporation.
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.
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.
Does evaporation cause cooling in the residual liquid?
yes
Why evaporating of water cause cooling?
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
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.
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
What is the definition of evaporation cooling?
mum
What is process cooling?
evaporation Cooling is a decrease of the temperature of a system or material.
How do you find out the effect of evaporation on skin?
Evaporation causes cooling . The skin cools when evaporation takes place.
How does evaporation causes cooling with examples?
sweating
How to calculate size and capacity of cooling tower?
calculation for cooling tower evaporation capacity.
How does evaporation help humans on ahot day?
evaporation helps us by cooling us down! :)
Would heating or cooling a pool decrease evaporation?
Heating a pool will increase the rate of evaporation from that pool.
The transformation of a liquid to a gas that serves as a cooling process is?
Evaporation
