Because dQ = dU+dW.
Where dU = MCv(T2-T1).
And dW = PdV = P(V2-V1).
So, at constant volume process work done is zero, as P(V2-V1) is zero.
Thus dQ = dU.
dQ = MCv(T2-T1).
Where dU = MCv(T2-T1).
And dW = PdV = P(V2-V1).
So, at constant volume process work done is zero, as P(V2-V1) is zero.
Thus dQ = dU.
dQ = MCv(T2-T1).
