5) Air, initially at 373 K, 1 atm , and V, = 1 liter undergoes two successive reversible expansions – a
reversible isothermal expansion to some intermediate volume V, , followed by a reversible adiabatic
a
expansion to a final volume V, =3 liters, cooling the gas to final temperature of 273 K. Calculate V, Q,
and W, for the process. Assume ideal gas behavior.
