Question

What is cohesive and adhesive force. Give some examples for each. ​

Answer 1

$\huge\mathfrak{\underline{\underline{\red {cohesive \: force}}}}</p><p>$

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.

$\huge\mathfrak{\underline{\underline{\red {Adhesive \: force}}}}</p><p>$

Similarly, the term "adhesive forces" refers to the attractive forces between unlike substance, such as mechanical forces (sticking together) and electrostatic forces (attraction due to opposing charges). In the case of a liquid wetting agent, adhesion causes the liquid to cling to the surface on which it rests.

Answer 2

Answer:

Liquids can, for example, be held in open containers because cohesive forces hold the molecules together. ... Attractive forces between molecules of different types are called adhesive forces. Such forces cause liquid drops to cling to window panes.
