TBL Individual Assignment 2 1) Consider the reversible Carnot cycle shown in the figure below. 2.00 mol of an ideal gas with C V,m = 5R/2 is the working substance inside the piston/cylinder assembly. The initial isothermal expansion occurs at the hot reservoir temperature of T hot = 850.0 K, from an initial volume V a = 30.00 L to V b = 60.00 L. The system then undergoes an adiabatic expansion until the temperature falls to T cold = 425.0 K at point c . It then undergoes an isothermal compression to point d and a subsequent adiabatic compression until the initial state of T a = 850.0 K and V a = 30.00 L is again reached. b. Calculate w , q, U and H for each step in the cycle and the total cycle. Hint: first think about which of the entries in the table must be zero without the need for any calculations (there are 8 of them). Stage w q U H a-b b-c c-d d-a total cycle FIG 5.13 (4TH EDITION, ENGEL&REID)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
