A helium weather balloon is released from ground level where the temperature is 20⁰ C. The balloon rises to a maximum height of 8.0 miles above the ground. At this height, the balloon expands to a volume that is 20 times greater than at the release point, and the pressure of the helium gas is 25 times smaller than at the release point. What is the final temperature, in ⁰F, of the gas at the maximum height of the balloon?

Initially 5.00 mol of helium (which we can treat as an ideal gas) occupies volume 0.120 m3 and is at temperature 20.0 ∘C. You allow the helium to expand so that its final volume is 0.480 m3 and its final temperature is also 20.0 ∘C. a)Calculate the net change in entropy of the helium if you make the helium expand isothermally from 0.120 m3 to 0.480 m3. b)Calculate the net change in entropy of the helium if you first increase...
