An ideal gas ...

Question

An ideal gas is made to go through a cyclic thermodynamic process in four steps. The amount of heat involved are $Q_{1} = 600 {J, Q}_{2} = - 400 {J, Q}_{3} = - 300 {J and Q}_{4} = 200 J$ respectively. The corresponding work involved are $W_{1} = 300 {J, W}_{2} = - 200 {J, W}_{3} = - 150 {J and W}_{4}$ .

Solution

The correct option is C $150 J$
$Δ Q = Δ U + Δ W$
$Δ U = 0$ (for cyclic process)
$\sum_{cycle} Q = \sum_{cycle} W$
$600 - 400 - 300 + 200 = 300 - 200 - 150 + W_{4}$
$⟹ W_{4} = 150 J$
