Calculate Heat Flow Work Done Change In Energy And Entropy For A Perfect Gas In Cycle


The figure given below shows the cycle followed by one mole of a perfect gas. Assuming each process is carried out reversibly.

(a) Name each process and calculate the pressure at each state.
(b) Write down the expression for the heat flow q, work done w, the change in internal energy ∆U and entropy change ∆S for each process.
(c) Calculate q, w, ∆U and ∆S for the complete cycle.



The question belongs to Chemistry and it discusses about calculating pressure, heat flow, work done, change in internal energy and entropy change for a perfect gas given in the cycle.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
