Question

The Volume V of a monoatomic gas varies with its temperature T , as shown in the graph. The ratio of work done by the gas, to the heat absorbed by it, when it undergoes a change from state A to state B , is, 1 3, 2 3, 2 5, 2 7

V ∝ T ⇒ Isobaric process W = P ∆ V = n R ∆ T ∆ Q = n C P ∆ T For mono atomic gas f = 3 C P = f 2 R + R = 5 2 R So W ∆ Q = n R ∆ T n C P ∆ T = 2 5
