The molecular theory accounts for the pressure exerted by a gas in a closed vessel as a result of the gas molecules striking against the wall of the vessel. How will the pressure change if : (a) the temperature is doubled keeping the volume constant, (b) the volume is halved, keeping the temperature constant?
