When a gas in taken from a to c along the curved path in Fig. 15-24, the work done by the gas is W = – 35J and the heat added to the gas is Q = – 63 J. Along path abc, the work done is W = – 48 J.
(a) What is Q for path abc?
(b) If Pc = ½ Pb, what is W for path cda?
(c) What is Q for path cda?
(d) What is Ua – Uc?
(e) If Ud – Uc = 5 J, what is Q for path da?
