Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

A helium-filled toy balloon has a gauge pressure of 0.250 atm and a volume of 10.0 L. How much greater is the internal energy of the helium in the balloon than it would be at zero gauge pressure?
Atmospheric pressure is 101000 Pa. A toy balloon is inflated with helium at a constant pressure...
Atmospheric pressure is 101000 Pa. A toy balloon is inflated with helium at a constant pressure that is 890000 Pa in excess of atmospheric pressure. If the balloon inflates from a volume of 0.00081 m^3 to 0.00101 m^3, how much work is done by the balloon on the surrounding air? Answer in units of J.
