In the figure below, the change in internal energy of a gas that is taken from A to C along the blue path is +805 J. The work done on the gas along the red path ABC is -565 J. (a) How much energy must be added to the system by heat as it goes from A through B to C? 565 Your response differs from the correct answer by more than 10%. Double check your calculations. J (b) If the pressure at point A is five times that of point C, what is the work done on the system in going from C to D? (c) What is the energy exchanged with the surroundings by heat as the gas goes from C to A along the green path? -565 Your response differs from the correct answer by more than 10%. Double check your calculations. J (d) If the change in internal energy in going from point D to point A is +570 J, how much energy must be added to the system by heat as it goes from point C to point D?
