Nitrous oxide (N2O), is a colourless gas with pleasant, sweetish odour and taste, which when inhaled produces insensibility to pain. It is used in specific proportions with oxygen as a pain relief gas or anesthetic gas. This compound is also known as laughing gas and inhaling it provides a brief euphoria effect. Nitrous oxide was discovered by the English chemist Joseph Priestley in 1772; another English chemist, Humphry Davy, later showed its physiological effect. A principal use of nitrous oxide is as an anesthetic in surgical operations of short duration. The gas is also used as a propellant in food aerosols. In automobile racing, nitrous oxide is injected into an engine’s air intake; the extra oxygen allows the engine to burn more fuel per stroke
