See attached diagram.

Inside a pot of boiling water, the hottest part of the water will be on the bottom. The water is in direct contact with the base of the pot, which is in contact with the burner/flame/coil. What does it mean if something is "hotter?" Heat is a form of energy, and the higher the heat of an object, the more energy it contains. When atoms gain energy, they become more unstable. They begin to move around more and become more active. This is why when you boil water, it begins to move fast and bubble.
