PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The attraction that causes water and other liquids to form drops on thin films is called ____ This is also water’s ability to be attraction to other water molecules.
A
Adhesion
B
Cohesion
C
Surface Tension
D
Capillary Action
Explanation: 

Detailed explanation-1: -This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Detailed explanation-2: -This property is called adhesion. 6. Hydrogen bonds hold water molecules closely together which causes water to have high surface tension. This is why water tends to clump together to form drops rather than spread out into a thin film.

Detailed explanation-3: -This is called adhesion because the attraction is to a different substance. In all systems within which water interacts with another surface, both adhesion and cohesion are factors.

Detailed explanation-4: -Detailed Description. Cohesion: Hydrogen Bonds Make Water Sticky. Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.

Detailed explanation-5: -Cohesion, also known as cohesive attraction or cohesive force, is the action or property of molecules adhering to one another due to mutual attraction. The force of attraction between two comparable substances or molecules is known as the cohesion force.
