Question

A gas expands from I to F in the figure below. The energy added to the gas by heat is 312 J when the gas goes from I to F along the diagonal path.

(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)

Р (atm) 10 A 8 B F 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 (2,9), extends vertically down to point B (2,5), then extends horizontally to point F 2 (8,5). • The blue path starts at point I (2,9), and extends down and to the right to end at point F (8,5). • The orange path starts at point I (2,9), extends horizontally to the right to point A (8,9), then extends vertically down to Uend at point F (8,5).
