NEET Physics Heat Engines Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) First Law of Thermodynamics | (i) Enthalpy change is path-independent |
| (b) Enthalpy of combustion | (ii) Energy conservation in isolated systems |
| (c) Change in internal energy | (iii) Heat released during combustion |
| (d) Hess's Law of Constant Heat Summation | (iv) ∆U = q + w |
a-ii, b-iii, c-iv, d-i
a-iv, b-i, c-ii, d-iii
a-iii, b-iv, c-i, d-ii
a-i, b-ii, c-iii, d-iv
Correct Answer
Detailed Explanation
The First Law of Thermodynamics states that energy conservation applies in isolated systems (a-ii), the Enthalpy of combustion refers to the heat released during combustion (b-iii), the change in internal energy is expressed as ∆U = q + w (c-iv), and Hess's Law states that enthalpy change is path-independent (d-i).
