Gases are a phase of matter, created when the temperature of a substance is above its boiling point.GASOLINE - This is a combination of many volatile liquids and gases extracted from petroleum. Its exact composition varies, but it is created by heating and fractional distillation.NATURAL GAS - Methane gas obtained from underground, or from petroleum. Methane is odorless but the chemical mercaptan (CH3SH) is added to enable detection by smell.INTESTINAL GAS - Gas that is swallowed into the digestive tract, or produced (as by fermentation) in the bowel.
