What are the two example of cohesion?

Answer 1

water droplets coming together when they are close together.

Answer 2

All forms of water (rain, in a glass, etc.) are examples of cohesion. Cohesion is a term used to coin the attraction between molecules of the same compound. Water is extremely cohesive being a polar molecule.

Answer 3

Cohesion (n. lat. cohaerere "stick or stay together") or cohesive attraction or cohesive forceis a physical property of a substance, caused by the intermolecular attraction between like-molecules within a body or substance that acts to unite them.Mercury exhibits more cohesion than adhesion

Water, for example, is strongly cohesive as each molecule may make four hydrogen bonds to other water molecules in a tetrahedral configuration. This results in a relatively strong Coulomb force between molecules. Van der Waals gases such as methane, however, have weak cohesion due only to Van der Waals forces that operate by induced polarity in non-polar molecules.

Cohesion, along with adhesion (attraction between unlike molecules), helps explain phenomena such as meniscus, surface tension and capillary action.

Mercury in a glass flask is a good example of the effects of the ratio between cohesive and adhesive forces. Because of its high cohesion and low adhesion to the glass, mercury does not spread out to cover the bottom of the flask , and if enough is placed in the flask to cover the bottom, it exhibits a strongly convex meniscus, where the meniscus of water is concave . Mercury will not wet the glass, unlike water and many other liquids ,[1] and if the glass is tipped, it will 'roll' around inside.

Answer 4

Two examples of cohesion are when water molecules stick together due to hydrogen bonding, forming surface tension, and when the plasma membranes of plant roots create a continuous column of water through capillary action.

Answer 5

cohesion: water forming a dome

adhesion: water clinging to a paper towels

Answer 6

water droplets coming together when they are close together.

Answer 7

water. Because living organisms need water to survive and water is cohesive.

Answer 8

water beads on the floor and water falls from the sky in the form of raindrops

Answer 9

water,glue,mud.
