A tank contains 25.0 kg of helium gas at a gauge pressure of 8.00 atm. What is the new gauge pressure after 5.0 kg of helium has been released to fill balloons? Assume the release is slow enough that the tank does not cool down. I am posting this because this question is listed three times on this website with three different answers (1.6 atm, 6.4 atm, and 10.25 atm)! They each say they have the right answer? Please take...
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?
