NEET Chemistry First Law Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) ∆U = q + w | (i) Law of conservation of energy |
| (b) w = 0 | (ii) Change in internal energy |
| (c) q = 0 | (iii) Isolated system |
| (d) ∆U = 0 | (iv) No heat transfer |
A
a-i, b-ii, c-iv, d-iii
B
a-i, b-iv, c-ii, d-iii
C
a-ii, b-iii, c-i, d-iv
D
a-i, b-iii, c-iv, d-ii
Correct Answer
Option A
Detailed Explanation
The equation ∆U = q + w is a mathematical statement of the first law of thermodynamics, which is the law of conservation of energy. When both w and q are zero, it indicates an isolated system, resulting in ∆U = 0.
