Match Column 1 (Physical variables) with Column II (Expressions). (n = number of gas molecules present per unit volume, kB = Boltzmann constant, T = absolute temperature, m= mass of the particle):
| Column I | Column II | ||
| (A) | Most probable velocity | (i) | \(n \mathrm{k}_{\mathrm{B}} T\) |
| (B) | Energy per degree of freedom | (ii) | \(\sqrt{\left(3 \mathrm{k}_{\mathrm{B}} T / m\right)}\) |
| (C) | Pressure | (iii) | \(\sqrt{\left(2 \mathrm{k}_{\mathrm{B}} T / m\right)}\) |
| (D) | vrms | (iv) | \(\mathrm{k}_{\mathrm{B}} T / 2\) |
- A→(iii), B→(ii), C→(i), D→(ii)
