Question

Why does your hand feel cool if you spill some alcohol on it?

Answer 1

It takes heat to make something evaporate, so it takes heat from your arm. Alcohol easily evaporates at room temperature, so it feels cool. This is also why you feel cool when getting out of the pool. The water on your skin evaporates.

Answer 2

The heat transfers from your warm hand to the alcohol. The energy leaving your hand causes it to “feel cold.”
