(II) A stoppered test tube traps 25.0cm 3 of air at a pressure of 1.00 atm and temperature of 18°C. The cylindrically shaped stopper at the test tube’s mouth has a diameter of 1.50cm and will “pop off” the test tube if a net upward force of 10.0N is applied to it. To what temperature would one have to heat the trapped air in order to “pop off” the stopper? Assume the air surrounding the test lube is always at a pressure of 1.00 atm.
