Temperature denotes the intensity of heat in a substance.
A milliliter of water and a liter of water may have the same temperature, but the heat in the liter of water will be a thousand times as great as the heat in the milliliter of water, because there is a thousand times as much water in the liter. The amount of heat in a substance is in direct ration to the volume or amount of the substance. In a report made in the 1930's the birthrates of the major nations of the world were compared to the death rates. In the United States there were six births for every four deaths. In England the ratio was smaller, with six births to every five deaths, and in the Soviet Union two births occurred for every death.
