NITROUS OXIDE :

Nitrous oxide [N20) is a colorless, odorless gas and was first discovered in 1793 by the English scientist Joseph Priestley. It is also known as "laughing gas". At room temperature, it is non-flammable with a pleasant and sweetest.
CHARACTERISTICS :
Nitrous oxide is relatively non-polar, has a low molecular weight, and high lipid solubility. The molecular weight of nitrous oxide is 44.01. The melting point is -90.81 and the boiling point is - 88.46.
N20 is a gas at room temperature, is 1 1/2 times denser than air, is colorless, tasteless, and has a slightly sweet odor. It is the only organic gas practical for clinical anesthesia. It is carried in the blood in solution only. It supports combustion as actively as oxygen when present with a flammable anesthetic.
APPLICATION & ITS USES :
Inhalant effects - It is a divisible drug that can cause analgesia, depersonalization, de- realization dizziness, euphoria, sound distortion and slight hallucinations
In medicine - It is regarded as a weak anesthetic so generally not used alone in general anesthesia.
Neuropharmacology - Medical grade nitrous oxide tanks used in dentistry.
Safety - Exposure to nitrous oxide causes short-term decreases in mental performance, audiovisual ability, and manual dexterity
