Question

Relation between van der waals constant and liquefaction

Answer 1

Explanation:

When a gas has a high value of the Van der Waals constant 'a', we can easily liquify the gas. So, we need less pressure for the liquefaction of this gas. When a gas has low value of the Van der Waals constant 'a', we cannot easily liquify the gas. So, we will need more pressure for the liquefaction of this gas.
