In the figure below, a monatomic ideal gas expands isothermally along AB and does 700 J of work, then expands adiabatically along BC and does 400 J of work. When the gas returns to A along CA it exhausts 100 J of heat. (a) Show the cycle on the T-s diagram. (b) Determine the total entropy change over the entire cycle. (c) If this cycle is for a heat engine, how much heat does the gas exchange along AB? how much work is done on the gas along the CA path? and what is the heat engine's efficiency?
