It's caused by so called Vad der Waals forces which are caused in its turn by dipole-single charge, dipole-dipole and so on interactions.

Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
the only electrical attractions that occur between oxygen molecules and water molecules are relatively weak dipole-induced dipole attractions.
When water is hot enough, the motion of the individual water molecules is fast enough to overcome the attraction that water molecules have for each other, which results in their escape from the liquid into the gas phase.
The type of attraction that holds two water molecules together is an electrostatic attraction, known as the hydrogen bond.
Cohesion is the force of attraction between molecules of the same substance which binds the particles together.
A large body of water molecules would typically not have a stronger attraction to fewer molecules. It would however attempt to pull smaller molecules toward it.
Cohesion- Is An Attraction Between Molecules Of The Same Substance.Adhesion- Is An Attraction Between Molecules Of Different Substances.
The attraction is: A POLAR COVALENT BOND
Small covalent molecules have a weak force of attraction.
cohesion
because halogen molecules are nonpolar. So, there is no development of permanent polarity.
