A tank 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 , 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.
