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?

Ideal Gas Law

Ideal gas law states that the product of pressure and volume of a gas directly varies with the product of the number of moles, the universal gas constant, and the temperature of the gas.
