Atank containing liquid butane and one containing liquid propane are sitting adjacent to one another. each tank is equipped with a regulator with a pressure gauge. classify these statements as true or false. the pressure reading for the butane tank is higher than that for the propane tank. the pressure readings will change when more liquid is added to the tanks. if the tanks are placed outside and the sun warms each tank to 46 âc, the pressure readings will be higher than they were initially. if an equal number of moles of gas is allowed to escape rapidly from each tank, the temperature of the butane tank will be lower than that of the propane tank.
