NEET Physics Isothermal & Adiabatic Processes Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Isothermal process | (i) q = 0, ∆U = w |
| (b) Adiabatic process | (ii) q = nR T ln(V_f/V_i) |
| (c) Reversible expansion | (iii) ∆U = 0 |
| (d) Free expansion | (iv) w = 0 |
a-iii, b-i, c-ii, d-iv
a-ii, b-iii, c-i, d-iv
a-iii, b-ii, c-iv, d-i
a-ii, b-i, c-iii, d-iv
Correct Answer
Detailed Explanation
In an isothermal process, the internal energy change (∆U) is zero, while in an adiabatic process, the heat transfer (q) is zero and the work done (w) equals the change in internal energy (∆U). The reversible expansion of an ideal gas follows the equation for work done involving logarithmic terms, while free expansion has no work done as the pressure external to the system is zero.
