Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Capillary action is the result of adhesion. Which aspect of water is responsible for this?
A
Nonpolar covalent bonds that enable water to dissolve other substances
B
Polar covalent bonds that join molecules of water to other substances
C
Hydrogen bonds between water and another substance
D
Ionic bonds that enable electrons to flow through water and into another substance
Explanation: 

Detailed explanation-1: -Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).

Detailed explanation-2: -Water is adhesive to the glass capillary tubes due to hydrogen bonding. The adhesion of the water to the glass causes the water to climb up the sides of the tube, forming a concave meniscus. Due to the strong surface tension of water, the entire liquid is carried up the capillary tube.

Detailed explanation-3: -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-4: -Answer and Explanation: Adhesion is created when water hydrogen bonds with other molecules, allowing water to creep or climb up surfaces.
