One cubic meter of an ideal gas at 600 k and 1000 kpa expand to five times its initial volume as follows:
(a) by a mechanically reversible, isothermal process [t 2 = 600k; p 2 = 200kpa; w= -1609 kj]
(b) by a mechanically reversible, adiabatic process [t 2 =208.96k; p 2 = 67.65 kpa; w= -994.4 kj] for each case calculate the final temperature, pressure and the work done by the gas. c p =21 jmol- 1k-1.
