A non-flammable, non-explosive gas (N2O) used as an oxidizing agent with gasoline or methanol to increase the rate and efficiency of combustion thereby increasing the horsepower.
This is a greenhouse gas commonly known as ``laughing gas''. It is composed of the two most common gases in the atmosphere: nitrogen and oxygen. It has an atmospheric concentration of 310 ppb (in 1990), as opposed to a pre-industrial 285 ppb (in 1880), although this relative scarcity belies its effectiveness as a greenhouse gas. A molecule of N O is 200 to 300 times more effective as is one of carbon dioxide as a greenhouse gas. It also has a longer residence time, being broken down into its constituents by light in the stratosphere after about 150 years. The main anthropogenic sources of atmospheric nitrous oxide are combustion (of fossil fuels, wood, or other biomass) and the widespread use of fertilizers, although the estimates for the amount supplied by the latter are highly variable. Natural sources include gas release into the atmosphere by the oceans and tropical and temperate forest soils.
A colorless gas, naturally occurring in the atmosphere. Nitrous oxide has a 100-year Global Warming Potential of 310.
Medical anesthetic gas, especially used in dentistry. Also called "laughing gas." Found in whipped cream dispensers and gas cylinders.
(NOx) One of the three basic pollutants found in the exhaust emission of an internal combustion engine. The amount of NOx usually varies in an inverse proportion to the amount of HC and CO.
A gas, N2O Nitrous oxide comes from biomass burning, fossil fuel burning, and the use of chemical fertilizers. It is of concern because in the troposphere it is a greenhouse gas and ill the stratosphere it contributes to ozone destruction.
a composed of two nitrogen molecules and one oxygen molecule. It is a bi-product of the natural process of vegetation decay, particularly rice paddies. It is released by nitrogen-based fertilizers which are heavily used today. Nitrous oxide is also produced by the burning of coal and the exhaust from cars. Nitrous oxide has the same effects of CFCs, but N2O molecules absorb 250 times as much heat as carbon dioxide.
is used as an anesthetic agent in medical, dental, and veterinary operatories. It is a weak anesthetic with rapid onset and rapid emergence. In hospitals, it may be used with oxygen as a carrier gas for other, more potent anesthetics. In dental offices, it is administered with oxygen, primarily as an analgesic (an agent that diminishes or eliminates pain in the conscious patient) and as a sedative to reduce anxiety.
an oxidizing, colorless, liquefied gas with a sweetish odor. It is toxic to humans when breathed. Nitrous oxide is used in the chemical vapor deposition of silicon dioxide and in plasma processes.
Nitrous oxide, a greenhouse gas. Nitrous oxide is released naturally from a wide range of biological sources in soils and the oceans. Nitrous oxide concentrations are increasing because of land-use changes, burning of vegetation, industrial emissions and fertiliser use.
N2O, a colorless, sweet tasting gas, used as a food aerosol and in anesthesia.
A greenhouse gas that is primarily released from intensive agriculture, and in automobile exhaust.

widely used anesthetic approved for use in dentistry and other medical procedures.
( N2O) Nitrous Oxide contributed 5% of direct global warming potential from UK national greenhouse gas emissions in 1990.
NO2, an atmospheric gas that traps infrared radiation and also can form nitric acid in rain droplets, resulting in acid rain.
(see laughing gas). Occlusal The uppermost chewing or grinding surface of a molar and/or premolar tooth.
one of the three major greenhouse gases responsible for climate change (see greenhouse gases). Soils and oceans are the primary natural sources of nitrous oxide. Humans contribute to nitrous oxide emissions through soil cultivation and the use of nitrogen fertilizers, nylon production and the burning of organic material and fossil fuels. Combustion and biomass burning are sources of nitrous oxide emissions. Agricultural practices may stimulate emissions of nitrous oxide from soils and play a major role in the build-up of nitrous oxide in the atmosphere.
(laughing gas) a gas used as an anesthetic in dentistry and other medical procedures.
A controlled mixture of nitrogen and oxygen gases (N2O) that is inhaled by the patient in order to decrease sensitivity to pain. Also referred to as laughing gas.
A potent greenhouse gas, the primary anthropogenic emissions of which are thought to come from agricultural fertilizers, and to a lesser degree, fossil fuel combustion and biomass burning. It is considered to be 320 times as powerful a greenhouse gas as CO2 over a 100-year time frame. Should be differentiated from oxides of nitrogen (NOx).
Also known as "laughing gas," this mixture of nitrogen and oxygen gases is given by inhalation to dental patients to alleviate anxiety and help to decrease pain sensitivity.
A long lived greenhouse gas with emissions created by industrial production such as in the making of nylon.
A colourless gas with a sweet taste and odor.
a gas used to relax patients. Also called laughing gas.
A colourless, slightly sweet-smelling, non-toxic gas which occurs naturally in the atmosphere. Man-made nitrous oxide is used as the anaesthetic commonly called "laughing gas".
A colorless naturally occurring and anthropogenically generated atmospheric greenhouse gas that contributes to the radiative warming of Earth ( cf. carbon dioxide).
N2O is a colorless, non-flammable potent greenhouse gas produced by natural processes also, but there are also substantial causal emissions from human activities such as deforestation, agriculture, trash burning and fossil fuel combustion. Nitrous oxide has a very high global warming potential.

N2O is among the six greenhouse gases to be curbed under the Kyoto Protocol. N2O is produced by natural processes, but there are also substantial emissions from human activities such as agriculture and fossil fuel combustion. The atmospheric lifetime of N2O is approximately 100 years, and its 100-year GWP is currently estimated to be 296 times that of CO2.
A colourless, non-flammable gas with a sweetish odour, commonly known as "laughing gas," and sometimes used as an anaesthetic. Oceans and rainforests naturally produce nitrous oxide. Nitrous oxide is produced by a range of human activities including: nylon and nitric acid production; the use of fertilizers in agriculture, use of catalytic converters in cars and the burning of organic matter. As are carbon dioxide and methane, nitrous oxide is a greenhouse gas.
