NEET Chemistry First Law Match the Following Question
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
Choose the correct matching:
a-i, b-ii, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-ii, b-iii, c-i, d-iv
a-i, b-iii, c-iv, d-ii
Correct Answer
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.
