Mathematical equation of first law of thermodynamics for isochoric process is

$\triangle U= q_{v}$

$-\triangle U= qv$

C) q=-W

$\triangle U= W$

Option A

For an isochoric process, $\triangle$ V=0

In this process, the first law of thermodynamics

q= $\triangle U-W$

q= $\triangle U-p \triangle V$

As $\triangle V=0$

qV= $\triangle$ U
