For a real gas, the van der Waals constant 'a' is zero. Can the gas the liquefied? Explain.

Text Solution

Verified by Experts

The van der waals constant 'a' measures the magnitude of intermolecular force of attraction in a gas. Hence, a real gas with 'a'=0 signifies that there is no intermolecular attractive forces in the gas. Consequently such a gas cannot be liquefied.
