A 6 centimeter diameter, 10 centimeter long cylinder contains 100 mg of oxygen (O2) at a pressure less than 1 atm. The cap on one end of the cylinder is held in place only by the pressure of the air. One day when the atmospheric pressure is 100 kPa, it takes a 194 Newton force to pull the cap off. Evaluate what is the temperature of the gas?
