Energy exchanged is used to do work and also to change internal energy

Vedclass · Answer

(A) An isochoric process is defined as a process where the volume of the system remains constant $(dV = 0)$.Since work done $dW = P dV$,if $dV = 0$,then $dW = 0$. Thus,no work is done in the process.According to the first law of thermodynamics,$dQ = dU + dW$. Since $dW = 0$,the heat exchanged $(dQ)$ is entirely used to change the internal energy $(dU)$ of the system.Therefore,statement $(A)$ is incorrect because energy exchanged is not used to do work.

In thermodynamics,for an isochoric process,which one of the following statements is $INCORRECT$?
