KH value for some gases at the same temperature 'T' are given:
KH is Henry's Law constant in water. The order of their solubility in water is :
| gas | KH/k bar |
| Ar | 40.3 |
| CO2 | 1.67 |
| HCHO | 1.83 × 10-5 |
| CH4 | 0.413 |
| 1. | Ar < CO2 < CH4 < HCHO |
| 2. | Ar < CH4 < CO2 < HCHO |
| 3. | HCHO < CO2 < CH4 < Ar |
| 4. | HCHO < CH4 < CO2 < Ar |
