PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The tendency of water molecules to attract to one another is known as
A
Adhesion
B
Cohesion
C
Specific heat
D
Capillary Action
Explanation: 

Detailed explanation-1: -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. Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.

Detailed explanation-2: -Adhesion: Water is attracted to other substances. Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.

Detailed explanation-3: -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-4: -Definition of Adhesion and Cohesion As for the definitions, the tendency of two or more different molecules to bond with each other is known as adhesion, whereas the force of attraction between the same molecules is known as cohesion.

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.
