NEET Chemistry First Law Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) ∆U = q + w (i) Conservation of energy (b) Isolated system (ii) Energy transfer is zero (c) Positive ∆U (iii) Energy is added to the system (d) Negative ∆U (iv) Energy is lost from the system
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-i, c-iv, d-iii
a-iv, b-ii, c-iii, d-i
Correct Answer
Detailed Explanation
According to the first law of thermodynamics, ∆U = q + w represents the conservation of energy in an isolated system, where energy can be added to (positive ∆U) or lost from (negative ∆U) the system.
