A balloon contains air at 25C and 1 atm pressure and has initial diameter of 0.5m. When it is filled with air isothermally and reversibly the pressure reaches 5 bar. Assume that pressure is proportional to the diameter of the balloon and calculate a) the final diameter of the balloon and b) the work done in the process

A helium-filled balloon at 1.00 atm pressure has a volume of 1.200 L. It is placed in a freezer and its volume decreases, stopping at 1.010 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.
