Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following properties of water enables molecules to cling together as they move from the roots to the leaves of plants?
A
Water expands as it freezes.
B
Water is an excellent solvent.
C
Water exhibits cohesive behavior.
D
Water moderates temperature.
Explanation: 

Detailed explanation-1: -Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it’s way all the way up to the branches and leaves.

Detailed explanation-2: -Cohesion: Hydrogen Bonds Make Water Sticky 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-3: -Cohesion of water 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-4: -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-5: -Water molecules are bent so the hydrogen atoms are to one side of the oxygen atom. and when it come to molecules opposites attract. A bond forms between the negative side of one water molecule and the positive side of another. At that is what gives water its stickiness.
