Methane, is a colourless, odourless gas that occurs abundantly in nature. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases. Methane is lighter than air, having a specific gravity of 0.554. It is only slightly soluble in water. It burns readily in air, forming carbon dioxide and water vapour; the flame is pale, slightly luminous, and very hot. Methane in general is very stable, but mixtures of methane and air, with the methane content between 5 and 14 percent by volume, are explosive. Explosions of such mixtures have been frequent in coal mines and collieries and have been the cause of many mine disasters. Methane is an important source of hydrogen and some organic chemicals.
