Figure 20-29 shows a reversible cycle through which 1.00 mol of a monatomic ideal gas is taken. Assume that p = 2p0, V = 2V0, p0 = 1.13*10^5 Pa, and V0 = 0.0235 m^3.

(a) Calculate the work done during the cycle.
J
(b) Calculate the energy added during stroke abc.
J
(c) Calculate the efficiency of the cycle.
%
(d) What is the efficiency of an ideal engine operating between the highest and lowest temperatures that occur in the cycle? (Note whether this is greater than or less than the efficiency calculated in (c).)

Q=n(Cp)deltaT
not sure how to use the graph to calculate anything. I don't know the first step to a solution. Any help would be greatly appreciated
