Question

The internal energy of a system does not change in a/an _____ process.
(A) Isothermal
(B)  Adiabatic
(C)  Isochoric
(D)   Isobaric

  1. A and C
  2. A and B
  3. B and D
  4. All of them

hintHint:

In case of isothermal, free expansion and cyclic process there is no change in the internal energy of the system as system's temperature remains constant in these processes.

The correct answer is: A and C


    Hence the answer is both  A and C. Both isothermal and isochoric does not change internal energy.
