People buying food in sealed bags at high elevations often notice that the bags are puffed up because the air inside has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of 22.0 °C. Whenopened at a summer picnic in Santa Fe, New Mexico, at a temperature of 32.0 °C, the volume of the air in the bag is 1.38 times its original volume. What is the pressure of the air?
