NEET Chemistry First Law Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Internal Energy Change (i) ∆U = q + w (b) Isolated System (ii) Energy is conserved (c) Spontaneous Process (iii) ∆G < 0 (d) Non-Spontaneous Process (iv) ∆G > 0
Choose the correct matching:
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-i, b-iv, c-ii, d-iii
a-iii, b-ii, c-i, d-iv
Correct Answer
Detailed Explanation
The first law of thermodynamics states that the internal energy change (∆U) is the sum of heat added to the system (q) and work done on the system (w). An isolated system retains constant energy, indicating conservation of energy. For spontaneous processes, the Gibbs free energy (∆G) is less than zero, while for non-spontaneous processes, ∆G is greater than zero.
