| Gas | O2 | N2 | NH3 | CH4 |
| a | 1.360 | 1.390 | 4.170 | 2.253 |
The gas which can be most easily liquefied is
Four gases P, Q, R and S have almost the same values of 'b' but their 'a' values (a, b are Van der Waals Constants) are in the order Q < R < S < P. At a particular temperature, among the four gases, the most easily liquefiable one is
Derive the values of critical constants in terms of van der Waals constants.
