(Ill) In the process of taking a gas from state a to state
Chapter 19, Problem 19.39(choose chapter or problem)
(Ill) In the process of taking a gas from state a to state calong the curved path shown in Fig. 19-32, 85 J of heatleaves the system and 55 J of work is done on the system.(a) Determine the change in internal energy, Ejnt a Ejnt c.(b) When the gas is taken along the path cda, the work doneby the gas is W = 38 J. How much heat Q is added to thegas in the process cda? (c) If Pa = 22P&, how much workis done by the gas in the process abc? (d) What is Q forpath abc? (e) If Eintj a - Eint; b = 15 J, what is Q for theprocess be? Here is a summary of what is given:Qa-c = 85 JWa_>c = -55 JWcda = 38 JEint, a E^t, b 15 JPa = 2.2 Pd.
