PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which force holds water molecules on the surface of cell walls?
A
Adhesion
B
Capilliarity
C
Cohesion
D
Surface tension
Explanation: 

Detailed explanation-1: -Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

Detailed explanation-2: -Cohesion holds hydrogen bonds together to create surface tension on water. Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Detailed explanation-3: -Water is highly cohesive-it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.

Detailed explanation-4: -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-5: -Water sticking to the cell walls of plants is an example of adhesion. This is a result of electrostatic forces existing between the water molecules and cell walls of plants. Adhesion is defined as the forces of attraction existing between water molecules and other substances that exhibit polarity.
