Volkswagen Golf Service & Repair Manual: Heat always flows from warmer to colder material
Every material consists of a mass of moving molecules. The fast moving molecules of a warmer material loose part of their energy to slower molecules possessing less heat. This slows down the molecules of the warmer material and accelerates those with less heat. This continues until the molecules in both materials are moving at the same speed. They have the same temperature, and no further exchange of heat occurs.
