Why is the polarity of water molecules and hydrogen bonding essential to adhesion and cohesion?

Answers

Cohesion and surface tension keep the hydrogen bonds of water molecules intact and support the item floating on the top. ... This is because the water molecules are attracted to the charged glass walls of the capillary more than they are to each other and therefore adhere to it.

Some properties like Polarity makes water a good solvent, cohesion helps in stick water molecule to itself while adhesion helps it to stick with other surfaces. Water have surface tension due to hydrogen bonding.

What are the difference between adhesion and cohesion ?

when two similar molecule come closer adhesion occur where as in cohesion two similar molecules face the force of attraction.

Adhesion is the force of attraction observed between the water molecules and xylem vessels while Cohesion is unrestrained among water molecules.

Capillary action and meniscus are the effects of adhesion while  Surface tension, meniscus and capillary action are the effects of cohesion.

The major forces responsible for adhesion are electrostatic or mechanical forces while Cohesion is the result of hydrogen bonding and Van der Waals forces.

A strong adhesion can lead to spread of liquid all over the surface while  cohesion forms water droplets.
