Transcribed Image Text:In the figure, 2.44 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 = 4.01 kPa and pc = 2.49 kPa, and the scale of the horizontal axis is set by Vpc = 4.55 m³ and Va =
2.86 m³. (The molecules rotate but do not oscillate.) During the transition along path ac, (a) what is the change in internal energy of the
gas, and (b) how much energy is added to the gas as heat? (c) How much heat is required if the gas goes from a to c along the indirect
path abc?
