Question

An ideal gas is taken through the cycle A → B → C → A , as shown in the figure. If the net heat supplied to the gas in the cycle is 5 J , the work done by the gas in the process C → A is, - 5 J, - 10 J, - 15 J, - 20 J

MARKS App · Accepted Answer

For cyclic process, Δ U = 0 ⇒ Q = W Q = W AB + W BC + W CA 5 = 10 × 1 + 0 + W C A ⇒ W C A = - 5 J
