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

In thermodynamics, for an isochoric process, which one of the following statement is INCORRECT?
  1. Energy exchanged is used to do work and also to change internal energy
  2. No work is done in the process
  3. It is a constant volume process
  4. Temperature of the system change during the process

Solution

In isochoric process, volume remains constant and hence no work is done. Energy exchanged is used to change in internal energy only. Hence statement (A) is incorrect.
