A thermodynamic cycle is shown below {where the coordinates of Point A are
(0.1m3, 5.0 E5 Pa) , Point B (0.5 m3, 1.0E5 Pa) and Point C (0.1 m3, 1.0 E5 Pa)} for an ideal gas in a piston. The system changes state from ABCA. A) what is the total work done by the gas during this cycle? B) How much heat is transferred? C) Does heat flow into or out of the system?
