NEET Physics Kinetic Interpretation of Temperature Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Average speed of lighter molecules | (i) Higher than heavier molecules |
| (b) RMS speed of nitrogen gas at 300 K | (ii) 516 m/s |
| (c) Boltzmann’s constant | (iii) Connects energy and temperature |
| (d) Mean square speed | (iv) Related to temperature |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-i, d-ii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
The average speed of lighter molecules is indeed higher than that of heavier molecules (a-i). At 300 K, the RMS speed of nitrogen gas is calculated to be 516 m/s (b-ii). Boltzmann’s constant is the proportionality constant that connects energy and temperature (c-iii), and the mean square speed is related to temperature (d-iv).
