Among the following the state function(s) is (are)
(i) Internal energy
(ii) Irreversible expansion work
(iii) Reversible expansion work
(iv) Molar enthalpy
  1. (ii) and (iii)
  2. (i), (ii) and (iii)
  3. (i) and (iv)
  4. (i) only

Solution

Internal Energy \((U)\) is a state function. It's value depends only on the initial and final positions.
Change in internal energy do not depend upon the path followed by the process. It only depends on initial and final states i.e
\(\Delta \mathrm{U}_1=\Delta \mathrm{U}_2\)
