Methane is a colorless and odorless chemical compound. that is abundant in nature and is in human body functions, it is the simplest alkane (which is a type of hydrocarbon) and it has the chemical formula CH4 .


Methane is lighter than air, having a specific gravity of 0.554 . It is only slightly soluble in water, and it is readily flammable in air, and when it burns it turns into carbon dioxide and water vapor . Here is the equation.

The boiling point of Methane is -162 celcius (-259.6 farenheit) and it's melting point is -182.5 celcius (-296.5 farenheit) . Methane in general is 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. Methane reacts with steam at high temperatures to yield carbon monoxide and hydrogen; the latter is used in the manufacture of ammonia for fertilizers and explosives. Other valuable chemicals derived from methane include methanol, chloroform, carbon tetrachloride, and nitromethane. The incomplete combustion of methane yields carbon black, which is widely used as a reinforcing agent in rubber used for automobile tires.
