Type: Match the Following-match the column-Easy-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Internal Energy Change, ∆U | (i) Depends on path taken |
| (b) Work Done, w | (ii) State function |
| (c) Heat, q | (iii) Path-dependent |
| (d) First Law of Thermodynamics | (iv) ∆U = q + w |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-iv, b-ii, c-iii, d-i
D
a-ii, b-iv, c-i, d-iii
Correct Answer
Option A
Detailed Explanation
Internal energy change (∆U) is a state function, which means it only depends on the initial and final states, not the path taken. In contrast, work (w) and heat (q) are path-dependent quantities. The first law of thermodynamics relates these quantities as ∆U = q + w.
