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 1.01 atm and a temperature of 21.0Ā°C. When opened at a summer picnic in Santa Fe, New Mexico, at a temperature of 31.0Ā°C, the volume of the air in the bag is 1.40 times its original volume. What is the pressure of the air (in atm)?
