Match List-I with List-II:
List-I | List-II |
---|---|
(A) Heat | (I) State function |
(B) Internal energy | (II) Path function |
(C) Work | |
(D) Entropy |
Heat and work are examples of path functions because they depend on the path taken by the system.
Internal energy and entropy are state functions as their values depend only on the current state of the system, not on the process used to reach that state.
LIST I | LIST II |
A. Subcooled water | I. 1 bar and 134°C |
B. Superheated steam | II. Dryness fraction = 1 and 100°C |
C. Steam at critical state | III. 20°C and 1.01325 bar |
D. Saturated steam | IV. 374.15°C and 220.8 bar |
