It is defined as the intermolecular force between the molecules.
It is considered as the weakest of all the intermolecular forces.
It depends on the surface area which means a molecule having the big size have greater vanderwall force.
For a real gas of n moles the vanderwall eqn. Is given as
(P+ an square /V2) (V-nb) = nRT
Here a and b are vanderwall constant.
V is volume
R is universal gas constant
T is temperature
n is no. Of moles

In molecular physics, the van der Waals force, named after Dutch scientist Johannes Diderik van der Waals, is a distance-dependent interaction between atoms or molecules. ... The term always includes the London dispersion force between instantaneously induced dipoles.
