Identifying limitations of kinetic-molecular theorya chemist 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, however, it deviates significantly from an ideal .

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
