A package of pretzels contains 0.145 L of air on the ground where the temperature is 24°C and the atmospheric pressure is 755 torr. If the temperature decreases to 17°C and the pressure decreases to 626 torr when the plane reaches its cruising altitude, what volume of air will be in the bag of pretzels?
Use (P1V1/T1) = (P2V2/T2) and Solve for V2. Don't forget that T must bre in kelvin. K = 273 + C
