In the figure, 1.79 mole of an ideal diatomic gas can go from a to c along either the direct (diagonal) path ac or the indirect path abc. The scale of the vertical axis is set by pab = 5.74 kPa and pc = 3.00 kPa, and the scale of the horizontal axis is set by Vbc = 4.85 m3 and Va = 2.32 m3. The molecules rotate but do not oscillate.) What is the net transfer of energy as heat for the indirect path?
