Question

what is cohesion ? give reason.

Answer 1

cohesion is water property that affect living and non-living things on earth through water molecules. Water is very cohesive in that it "sticks" to itself. Cohesion is what allows a water droplet to form, for example. When water molecules surround one another, they settle toward a low energy state.

Cohesive forces are the intermolecular forces (such as those from hydrogen bonding and Van der Waals forces) which cause a tendency in liquids to resist separation. This attractive force exist between molecules of the same substance

Answer 2

Cohesive are the atractive forces that exists between the molecules of the same substance.
For instance, rain fas in droplets rather than a fine mist, because water has strong cohesion which pulls its molecules tightly together, forming droplets.
