temperature is defined to be the average kinetic energy.
heat energy tends to flow from higher energy to lower energy systems, so knowing the temperatures of things tells you how heat will flow between them.
EXAMPLE --------> when you step on a very hot pavement with your bare feet that makes you move a lot faster
