A propellant is a chemical which is used in the production of energy and pressurized gas that is used to create movement of a fluid or to generate propulsion of a vehicle or projectile or other object. Common propellants are energetic materials and consist of a fuel; like gasoline, jet fuel, rocket fuel, and an oxidizer. Propellants are burned or otherwise decomposed to produce the propellant gas. Other propellants are simply liquids that can readily be vaporized.
