The molecules in any substance do not have exactly the same energy: there are those with more (hot) and those with less (cool). Temperature is a function of the distribution of energy through the molecules: the higher the overall energy of the molecules, the higher the temperature.
Evaporation occurs when the higher energy (hot) molecules leave the substance exactly because their energy is above average (they are too hot). This leaves behind lower energy molecules (cooler molecules) which, in turn, means that the overall energy of the substance diminishes. Another way of putting it: leaving behind cooler molecules means the temperature goes down closer to them.
Its a heat exchange. like the high energy molecule evaporate and then the low energy remain in the material low energy means cool molecules remain at the surface. its a cooling process in this way.

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
Is alcohol evaporation endothermic or exothermic?
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.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
Does evaporation cause cooling in the residual liquid?
yes
What process cools the ocean?
Evaporation.
What is process cooling?
evaporation Cooling is a decrease of the temperature of a system or material.
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
The transformation of a liquid to a gas that serves as a cooling process is?
Evaporation
Evaporation is a cooling process because?
heat is radiated away
Why is evaporating from water from your skin a cooling process?
Evaporation is an endothermic process, absorb energy.
Is heat energy being added or removed during the process of evaporation?
In condensation heat is removed In evaporation heat is added
Is condensation a cooling or warming process?
Condensation is the opposite of vaporization. When you sweat you are cooling your body off; therefore condensation is a warming process. Or Evaporation A+
What is evaporation condensation?
Evaporation is the process of water becoming a vapour. Condensation is the cooling of the water vapour back into a liquid.
Evaporation is a cooling process and condensation is?
Condensation is a warming process.
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
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 do your bodies use evaporation to cool ourselves?
Because it takes away the heat energy used by it to evaporate. Evaporation its self is a cooling process.
