What does really happen during evaporation,
The temperature of the liquid falls
Or
The temperature of the liquid rises

Evaporation occurs when a liquid absorbs heat from the surroundings, which should make the avg. temperature of the liquid rise from its initial level, making the surrounding cooler and not itself.But in a MCQ it was put the other way around.If the contrary is true then why?

Evaporation occurs when a liquid absorbs heat from the surroundings

No. Evaporation consumes heat regardless of whether a liquid is heated or not. If liquid is in an open, but otherwise thermally isolated container, it will still evaporate and its temperature will go down.

[Darren]

The temperature of the liquid will decrease as it evaporates. Evaporating occurs at the surface when there are some molecules in the liquid having enough energy to escape the liquid surface. There is not heat absorbed in this way as the molecules already have their kinetic energies. Thus, they leave the surface of the liquid and the overall kinetic energy of the liquid decreases and temperature decreases.
