Question

What is crude oil??? And what is natural gas???

Answer 1

Crude oil and natural gas are mixtures of hydrocarbons-chemical molecules that contain only hydrogen and carbon. Crude oil is a liquid both underground and at normal surface conditions. Natural gas is a vapor at normal surface conditions; underground, it can exist either as a vapor or something like a bottle of carbonated soda-"in solution" with crude oil until the pressure is reduced.

The term "petroleum" collectively refers to crude oil, natural gas and solid hydrocarbon mixtures like tar and asphalt. In addition to hydrocarbons, petroleum may contain impurities such as water, sulfur compounds, oxygen, nitrogen, carbon dioxide and traces of metals.
