Evaporative Cooling

Over the cup of boiling water you can see steam rising up, this steam helps in the process of evaportive cooling as it releases heat in the form of that steam to cool the water faster.

Evaporative cooling is the process that helps remove heat from certain objects in a form of releasing heat energy. As objects release steam or other hot vapors they release many of their heat atoms from the object itself slowly causing it to lose energy allowing it to grow colder over time as more energy is released. This form of cooling takes place in both liquid and solid objects such as foods or beverages.
