Petroleum is an oily combustible liquid. It is usually dark in colour and has a distinctive odour. It is much lighter than water and does not dissolve in water.
There are several theories of the origin of oil, as petroleum is often called. Many scientists consider that petroleum was formed in remote epochs by the decomposition of plant and animal organisms out of contact with air.
Like natural gas, petroleum is a mixture of hydrocarbons, only of higher molecular weight. Petroleum consists for the most part of liquid hydrocarbons, but there are gaseous and solid hydrocarbons dissolved in them.
