Does anyone have an argument to that way of looking at it?

Chilling Science: Evaporative Cooling with Liquids

WebThese are relatively weak, and there are always some H 2 O molecules whizzing around with enough energy to break free of their neighbours, even at temperatures well below 100°C. These can then escape – ‘evaporate’ – into the air. Even more evaporation will take place if the surrounding air pressure is reduced, for example by going to ... WebSep 8, 2024 · Evaporation: A Cooling Process For water molecules to go from a liquid to an energized gaseous state, they must first absorb heat energy. They do this by colliding with other water molecules. Evaporation is called a “cooling process” because it removes heat from the surrounding air.
