##### Reference no: EM131293922

Helium at 70.0°F enters a 3.00 ft3 rigid tank that is filled to a final pressure of 2200. psia.

Assuming the tank is initially evacuated and that the helium behaves as an ideal gas with constant specific heats, determine the amount of entropy produced when the tank is filled (a) adiabatically and (b) isothermally at 70.0°F.
