Question

Can a Van der Waals gas with a = 0 be liquefied? Explain

Answer 1

• a = 0, for a Van der Waals gas i.e. for a real gas. Van der Waals constant a = 0. It cannot be iquefied. 
• If a = 0, there is a very less interaction between the molecules of gas. 
• ‘a’ is the measure of strength of Van der Waals force of attraction between the molecules of the gas. 
• If a is equal to zero, the Van der Waals force of attraction is very less and the gas cannot be liquefied
