Which Statement Is True About Van Der Waals Forces?

Which of the following statements concerning van der Waals forces is correct?When the forces acting on a substance are weaker, the substance’s volatility will increase.When the forces acting on a substance are greater, the viscosity of the substance decreases.The boiling point of a material will be greater when the forces acting on it are weaker.When the forces acting on a substance are lesser, the substance’s volatility will be greater.

Van der Waals forces are cumulative in nature and cannot be completely exhausted.They do not have any distinguishing characteristics in terms of direction.Because these are all short-range forces, only interactions between the closest particles must be taken into account when calculating the total force (instead of all the particles).When molecules are close together, the van der Waals attraction is stronger.
