What is force of cohesion?
cohesion, in physics, the intermolecular attractive force acting between two adjacent portions of a substance, particularly of a solid or liquid. It is this force that holds a piece of matter together. Intermolecular forces act also between two dissimilar substances in contact, a phenomenon called adhesion.
What is difference between cohesion and adhesion?
As for the definitions, the tendency of two or more different molecules to bond with each other is known as adhesion, whereas the force of attraction between the same molecules is known as cohesion.
