Does liquid absorb or release heat when heated?

As a liquid is heated, its molecules absorb heat and move faster. When the liquid starts to boil, bubbles of vapor form within the liquid and rise to the surface. The temperature that causes this to happen is known as the boiling point of a liquid.

What happens when a volume of fluid is warmed at the bottom?

First, the liquid on the bottom of the pot closest to the heat source starts to get hot; as it does, it rises. The rising hot water is replaced by the cooler, more dense water molecules. The bubbles rise, due to buoyancy, and then collapse as they reach the denser, relatively cooler water at the surface of the pot.
