Question

for what reason we laugh after smelling Nitrous oxide​

Answer 1

Answer:

Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain reducing effects. Its 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.

Answer 2

Answer:

Explanation: Nitrous oxide enters the blood by diffusion from the alveoli whilst it is being inhaled, but does not bind with haemoglobin. It is fat soluble so quickly moves into cells, including synapse ends in the brain. Because of the stability of the compound, N2O is not metabolised by the body so has its effect as that molecule, then is eliminated by diffusion out of the lungs once inhalation has ceased
