47. We note that there is no work done in the process going from d to a , so Q da = Δ E int da = 80 J. Also, since the total change in internal energy around the cycle is zero, then Δ E int ac + Δ E int cd + Δ E int da = 0 200 J + Δ E int

Unformatted text preview: cd + 80 J = 0 which yields E int cd = 120 J. Thus, applying the first law of thermodynamics to the c to d process gives the work done as W cd = Q cd E int cd = 180 J 120 J = 60 J....
