Question:

The pV-diagram in Fig. 20.5 shows a cycle of a heat engine that uses 0.250 mole of an ideal gas having y = 1.40.

The curved part a of the cycle is adiabatic.

(a) Find the pressure of the gas at point a.

(b) How much heat enters this gas per cycle, and where does it happen?

(d) How much work does this engine do in a cycle?

(e) What is the thermal efficiency of the engine?
