Thermodynamic Processes

$dQ$ is the heat energy supplied to an ideal gas under isochoric conditions. If $dU$ and $dW$ denote the change in internal energy and the work done respectively then

Show answer and solution

Answer: (d)

Isochoric: $dV = 0 \Rightarrow dW = P\,dV = 0$ .
First law: $dQ = dU + dW = dU$ .
So the answer is (d) $dQ = dU$ .
