NEET Physics Laws of Thermodynamics Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) First Law of Thermodynamics (i) ∆G < 0 indicates spontaneity (b) Second Law of Thermodynamics (ii) Energy cannot be created or destroyed (c) Enthalpy Change for an exothermic reaction (iii) ∆H < 0 (d) Spontaneity of a reaction (iv) Entropy of an isolated system increases
Choose the correct matching:
a-ii, b-iv, c-iii, d-i
a-i, b-ii, c-iv, d-iii
a-iii, b-i, c-ii, d-iv
a-iv, b-iii, c-i, d-ii
Correct Answer
Detailed Explanation
The First Law of Thermodynamics states that energy cannot be created or destroyed, which matches with (a) and (ii). The Second Law states that the entropy of an isolated system always increases, matching (b) and (iv). For an exothermic reaction, the change in enthalpy (∆H) is negative, matching (c) and (iii). Lastly, a reaction is spontaneous when ∆G is negative, matching (d) and (i).
