Question

what is van der waals force

Answer 1

Answer:

Van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids.The tendency of such permanent dipoles to align with each other results in a net attractive force.

Explanation:

here's the formula

F_{VW}(r)=- \frac {AR_1R_2}{(R_1+R_2)6r^2}

F_{VW} = van der Waals force

R_1, R_2 = spherical bodies radii

A = Hamaker constant

r = the distance between the surfaces
