(a) Show that the heat transferred during an infinitesimal quasi-static process of an ideal gas can be written
Applying this equation to an adiabatic process, show that PP = const.
(b) An ideal gas of volume 0.05 ft3 and pressure 120 Ib/in2 undergoes a quasi-static adiabatic expansion until the pressure drops to 15Ib/in2. Assuming, to remain constant at the value 1.4, calculate the final volume. Calculate the work.
