Problem 16.06 (Figure 1) shows a pV diagram for a heat engine that uses 1.40 moles of an ideal gas. The internal energy of the gas changes by the following amounts: ΔUa→b = +5050 J, ΔUb→c = -6060 J, ΔUc→d = -1010 J, and ΔUd→a = +2020 J Part E How much work does this engine do each cycle? Express your answer in joules to three significant figures. Part F What is the thermal efficiency of the engine? Express your answer as a percentage to two significant figures.
