Question

'evaporation causes cooling '.comment on this statement

Answer 1

It is very true that evaporation causes cooling because when evaporation takes place it uses the latent heat of vaporisation to evaporate making the surface area to feel cool. For example, when we put some acetone on our palm, it evaporates taking the latent heat of vaporisation from our palm and help our palm to feel cool.

Answer 2

Evaporation causes cooling,this statement is completely is true.

Because, any evaporation process needs a certain amount of heat energy.And it mainly takes out the latent heat, that's why the whole body becomes cooler than before.

That's why the statement mentioned in the question is justified.
