Why do liquids evaporate below their boiling temperature.

1.32K views

Water’s boiling temperature is 100C or 212F, when you spill some on concrete or leave a cup of water outside, it disappears without it reaching 100C even if it is in the shade. The water from the ocean also evaporates, but it is not boiling. This happens with other liquids to such as isopropyl alcohol, or gasoline.

How does this happen?

think of boiling as forced evaporation, a temperature where no liquid phase can exist.

at all temperatures below that, the thing, say water, can exist in both a liquid and a gas form. and evaporation is just individual molecules getting enough energy to become a gas one by one.

Boiling is sending a bunch of energy in a forcing all the molecules to turn to gas.
