Achemist is studying the properties of a gas under various conditions he observes that when the gas is at room temperature and low pressure it behaves as an ideal gas when the gas is cooled to 10 kelvin and is placed under high pressure how ever it deviates significantly from an ideal gas explain these observations

the millers tale is the answer.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it means there are 3 atoms of oxygen
