Description
Nitrous oxide is nontoxic,nonflammable , colorless gas with a slightly sweet taste and odor . The odor is subjective and therefore not reliable , and should not be used to detect the presence of the gas . It is stable and nonreactive under normal conditions, but becomes a strong oxidizing agent at elevated temperatures and pressure . Nitrous oxide is shipped as a liquefied gas under its own vapor pressure.
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, nitro, or nos,is a chemical compound, an oxide of nitrogen with the formula N2O. At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen.
Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain-reducing effects.Its colloquial name, "laughing gas", coined by Humphry Davy, is due to the euphoric effects upon inhaling it, a property that has led to its recreational use as a dissociative anaesthetic.It is on the World Health Organization's List of Essential Medicines.It is also used as an oxidiser in rocket propellants, and in motor racing to increase the power output of engines.Nitrous oxide's atmospheric concentration reached 333 parts per billion (ppb) in 2020, increasing at a rate of about 1 ppb annually.It is a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs.About 40% of human-caused emissions are from agriculture.Nitrogen is added to the soil via animal urine and dung, and synthetic fertilisers: micro-organisms then release it in nitrous oxide.Being the third most important greenhouse gas, nitrous oxide substantially contributes to global warming.Reduction of emissions is a popular topic in the politics of climate change.Nitrous oxide is used as a propellant, and has a variety of applications from rocketry to making whipped cream.
