A sealed test tube traps 25.9 cm3 of air at a pressure of 1.00 atm and temperature of 17?C. The test tube's stopper has a diameter of 1.50 cm and will "pop off" the test tube if a net upward force of 10.4 N is applied to it. To what temperature would you have to heat the trapped air in order to "pop off" the stopper? Assume the air surrounding the test tube is always at a pressure of 1.00 atm.
