A heat engine is described by the thermodynamic cycle shown in the figure on the right. Find the change of internal energy, the net heat transfer, and the work done BY the gas after one cycle. What is the efficiency of the engine? Explain. No equations, graphs or sketches allowed. HINT 1: You should be able to obtain numerical values for all questions. HINT 2: If confused (but only as a last resort!), try inventing your own numbers on the axes, and then calculating numerically all quantities to inform your intuition before you start explaining. Of course, your explanation should not refer to your invented numbers.
