If, when the temperature is several degrees below zero, a piece of ice is brought into a warm room, its temperature rises until it is at zero. If now more heat is applied to it, it melts to a liquid, then heats to 100°, and then boils away. In the course of this process there has been one change of the body from a solid to a liquid, and another from a liquid to a vapor. A similar change of physical condition can be brought about with most solid bodies if only the proper change of temperature can be produced.
