PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When water molecules stick to other water molecules, this is called-
A
cohesion
B
adhesion
C
surface tension
D
capillary action
Explanation: 

Detailed explanation-1: -In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

Detailed explanation-2: -Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself. and adhesion means that water likes to stick to other things.

Detailed explanation-3: -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: -This is because the water molecules are attracted to the charged glass walls of the capillary more than they are to each other and therefore adhere to it. This type of adhesion is called capillary action.
