In thermodynamics, for an isochoric process, which one of the following statement is INCORRECT? (a) Energy exchanged is used to do work and also to change internal energy. (b) No work is done in the process. (c) It is a constant volume process. (d) Temperature of the system changes during the process.

Answer: (a). Isochoric: volume constant (c true), so W = 0 (b true). All heat changes U, so the temperature changes (d true). Statement (a) says energy also does work, which is false. So the INCORRECT statement is (a).

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

Show answer and solution

Answer: (a)

Isochoric: volume constant (c true), so $W = 0$ (b true).
All heat changes $U$ , so the temperature changes (d true).
Statement (a) says energy also does work, which is false.
So the INCORRECT statement is (a).
