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?

Boiling temperature is just the temperature at which material no longer exists in liquid form. All liquids evaporate at most temperature/pressure combinations – all it takes is enough energy to excite a molecule on the boundary layer between the liquid and its gas environment.
