A type of gas is a classification in which a gas falls under that describes its properties. Gases can be classified as oxidizers, inert gases and flammable gases.
Oxidizing gases are not flammable gases but contribute to a combustion reaction. They should not be used in combination with fats or oils. Inert gases do not react with other substances and do not participate in combustion reactions. When an inert gas is emptied into a room or space, it reduces the amount of oxygen present and limits the process of combustion. This principle is applied in extinguishing systems. Flammable gases combine with air or oxygen and burn or explode.
A gas is one of the three states of matter, including solids and liquids. Gas particles contain large amounts of energy but are less organized than particles of other matter states. They are spread out over a greater distance and move more randomly. Gas has the ability to expand or compress to fill a container. This is done with a manipulation of the pressure of the gas as well as changing the temperature. Gases move from areas of high pressure to areas of lower pressure. If a gas is a liquid at room temperature, it is referred to as a vapor.
