. Helium gas is compressed from 90 kPa and 30 C to 450 kPa in a reversible, adiabatic (i. e., isentropic) process. Determine the final temperature and the work done (kJ/kg), assuming the process takes place (a) in a piston-cylinder device and (b) in a steady-flow compressor. (You may take the specific heat of He to be cp = 2.5*Rg where Rg = Ru/MW.)
