WebApr 10, 2024 · Evaporation causes cooling because the process requires heat energy. The energy is taken away by the molecules when they convert from liquid into gas, and this causes cooling on the original surface. Heat and Evaporation When a liquid evaporates, its molecules convert from the liquid phase to the vapor phase and escape from the surface. WebJun 14, 2024 · That’s why, if you leave a glass of water out in a 70-degree room, the water temperature will be cooler than 70 degrees. If swimming-pool water is evaporating off your skin, each water molecule is grabbing a tiny bit of your body heat in order to make its phase change from liquid to gas. Your body loses heat, and feels cooler.
