Answer in Brief

Solution

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