What is it called when water take a long time to cool down

i think precipitation?

Explanation:

How long will it take for the boiling water to cool down to 45 °C in an open pot if the room temperature is 22 °C? Cooling from 100 to 45 in a closed container, not sealed so you don’t get a vacuum, probably takes 100 minutes or so. but you said open pot, so it’s faster, as you get material loss (evaporation/”sensible heat”) as the water cools.

can you make it bigger i can't see it
