Theory best represents the models that explain and give the underlying causes for conclusions drawn from many years of experimental evidence

Explanation:

A theory is a collection of standard ideas or established principles that define and manage the review. Another way of describing the theory is that it is distinct from work when some principles are tested. A set of statements or principles devised to describe a collection of facts or phenomena, particularly one that has been frequently examined or is widely believed and can be used to make forecasts about natural phenomena.

A theory not only describes known facts; it also allows scientists to make forecasts of what they should recognize if a theory is true. Scientific theories are testable. New evidence should be compatible with the theory.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
