D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: D
Solution :
According to first law of thermodynamics, \[\Delta Q=\Delta U+\Delta W=\Delta U+P\Delta V\]. If heat is supplies in such a manner that volume does not change \[\Delta V=0\] i.e., isochoric process, then whole of the heat energy supplied to the system will increase internal energy only. But, in any other process it is not possible. Also heat may absorbed or evolved when state of thermal equilibrium changes.You need to login to perform this action.
