solve problem number 28.

is the answer b or c?

argument for b: b is the point of the highest pressure, and lowest volume in the process, it should produce the highest temperature.

argument for c: applying the fact that in a PV diagram, the product of P*V (x and y-coordinate) is nRT (according to the ideal gas law), since nR is constant in the cyclic process, then highest temperature point is found by comparing the P*V at point b and at point c. P*V at point b is 3, and P*V at point c is 9, then by this method point c produce the highest temperature.

So the question is that whether Ideal Gas Law is applicable in this case?
