Question

Why vanderwaals force is stronger near critical temperature?

Answer 1

Answer:

At a temperature greater than the critical temperature, the gas molecules are far apart from each other, they have high kinetic energy are can move freely, so they have very weak force of attraction between them. Further the vanDer Wall forces becomes weaker as the temperature increase

Answer 2

Answer:

At a temperature greater than the critical temperature, the gas molecules are far apart from each other, they have high kinetic energy are can move freely , so they have very weak force of attraction between them. Further the van der Wall forces becomes weaker as the temperature increase.
