5. [2/5 Points] DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER Start here Th ,2 3 V Consider the graph of a carnot cycle in answering each question. All steps are reversible. Assume the working fluid is an ideal gas with Th = 1834K and an efficiency of 0.73. a) Compute the temperature of the cold sink. To = 495.18 K. b) In which step (1-4) is the heat, q, the smallest value? O step 1 O step 2 O step 3 O step 4 c) If the entropy decreases by 1.94 J/K, compute the amount of heat released (wasted) by the engine. 960.65 d) Compute AS2. D/K e) The notion that heat must be wasted in the cycle as shown is connected to the fact(s) that (check all that apply) the theoretical efficiency cannot be 100% O nature charges an entropy tax because there is friction the total entropy must increase Viewing Saved Work Revert to Last Response
