Properties of Natural Gas

Natural Gas is a naturally-occurring mixture of hydrocarbon and non-hydrocarbon gases found in porous formations beneath the earth's surface. It is not a pure element like oxygen, but a mixture of gases of which hydrocarbon gases are the components that are combustible and produce heat. Natural gas distributed by utilities varies in composition.
