Why is acetone cold?
2
Answers
Acetone is a very volatile solvent, meaning that it evaporates quickly. Heat is absorbed from whatever surface the acetone molecules are found on, and as they take heat from that surface and evaporate, the surface, feels cold because it's lost energy in the form of heat.

It's not that acetone is cold per se, but because evaporation is an endothermic phenomenon, the acetone molecules absorb heat in order to evaporate. The heat is absorbed from whatever surface the acetone molecules are found on. The surface feels cold because its lost energy in the form of heat.
