Question

A gas expands from I to F in the figure below. The energy added to the gas by heat is 422 J when the gas goes from I to F along the diagonal path.

Three paths are plotted on a PV diagram, which has a horizontal axis labeled V (liters), and a vertical axis labeled P (atm).

The green path starts at point I (2,4), extends vertically down to point B (2,1), then extends horizontally to point F (4,1).
The blue path starts at point I (2,4), and extends down and to the right to end at point F (4,1).
The orange path starts at point I (2,4), extends horizontally to the right to point A (4,4), then extends vertically down to end at point F (4,1).

(a) What is the change in internal energy of the gas?
J

(b) How much energy must be added to the gas by heat for the indirect path IAF to give the same change in internal energy?
J
