When two bodies are brought in contact with each other, each communicates a part of its molecular energy, or heat, to the other. If the two bodies are of the same temperature, each receives as much as it imparts, and there is no change in the temperature of either. If, however, the body A is of a higher temperature than the body B, it gives more heat than it receives, and its temperature is lowered by an amount which depends upon the difference between the two temperatures; while the body B has its temperature raised, and we say heat has been transmitted to it. Heat can be transmitted in three ways by conduction, by convection, and by radiation.
