Thermodynamic processes

Question

An ideal gas is taken through the cycle $A \to B \to C \to A,$ as shown. If the net heat supplied to the gas in the cycle is 5J, the work done by the gas in the process $C \to A$ is

Moderate

A

-5 J
B

-10 J
C

-15 J
D

-20 J

Solution

For cyclic process $Δ U = 0$
$\begin{array}{l} So, Δ Q = Δ W \\ 5 = Δ W_{A B} + Δ W_{B C} + Δ W_{C A} \\ 5 = 10 + 0 + Δ W_{C A} \\ Δ W_{C A} = - 5 J \end{array}$
