Answer to Problem 5E

The heat is transferred from the ashes to the surrounding particles.

Explanation of Solution

Mostly the fire is a combination of hot gases which become the part of the surrounding atmosphere. The left-over ashes are the substances which are not transformed into heat or light by a fire. The ashes heat transfers into the surrounding air and other materials around the atmosphere. This is the reason for ashes of fire to cool down, overnight.
