Vander Waals Forces

                 Attractive forces between uncharged molecules are known as vander-waals forces.             ( vanderwaals forces include attractions between atom, molecule and surface as well as other inter molecular forces ).
                                 (P  +  a/V2)    V  -  b   =  RT
P  ==> Pressure
a  ==> Attraction between individual gas particle.
V ==> Volume
b  ==> Average volume of individual gas particles.
R ==> Ideal gas constant.
T ==> absolute temperature.
