Exercise 46

On a warm day (92°F), an air-filled balloon occupies a volume of 0.200 m 3 and has a pressure of 20.0 lb/in 2. If the balloon is cooled to 32°F in a refrigerator while its pressure is reduced to 14.7 lb/in 2 , what is the volume of the air in the container (Assume that the air behaves as an ideal gas.)
