Which of the following statements are TRUE with respect to heat and work?
(i) They are boundary phenomena
(ii) They are exact differentials
(iii) They are path functions
-
- both (i) and (ii)
- both (i) and (iii)
- both (ii) and (iii)
- only(iii)
Correct Option: B
Since heat and work are energy in transit i.e. heat and work has meaning only when there is process. So both are boundary phenomena and are inexact i.e. path function.
