N2O, commonly known as nitrous oxide, is a colorless gas with a slightly sweet odor. It is used in various applications, including as an anesthetic in dentistry and as a propellant in whipped cream dispensers. N2O is also a greenhouse gas, contributing to climate change when released into the atmosphere. In addition to its medical uses, nitrous oxide is utilized in the automotive industry to enhance engine performance. When injected into an engine, it increases power output by providing more oxygen for combustion. However, its use must be managed carefully due to potential environmental impacts.
