If not, why not? What three criteria must be met for a molecule to escape from the surface of the liquid and move into the gas phase? c. If you spill some nail polish remover on your hand, the spot will soon feel cold. Why? d. If you spill some acetone on a lab bench, it evaporates much faster than the same amount of acetone in a test tube. Why? e.
