*98. GO An ideal gas is taken through the three processes (A →B, B →C, and C → A) shown in the drawing. In general, for each process the internal energy U of the gas can change because heat Q can be added to or removed from the gas and work W can be done by the gas or on the gas. For the three processes shown in the drawing, fill in the five missing entries in the following table. A Volume Process AU W A →B (b) +561 J (a) B →C +4303 J (c) +3740 J C→A (d) (e) - 2867 J Pressure B.
