PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water’s ability to stick to glass is
A
adhesion
B
cohesion
C
surface tention
D
capillary action
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Water and glass have a smaller attractive force, called adhesion rather than cohesion to distinguish the intermolecular forces between two separate bodies (glass attracting water) from those of water attracting water. Adhesion between water and glass leads to capillary rise in a glass tube.

Detailed explanation-3: -Capillarity starts when the water molecules nearest the wall of the tube are attracted to the tube more strongly than to other water molecules. The water molecules nearest the glass wall of the tube rise up the side (adhesion), dragging other water molecules with them (cohesion).

Detailed explanation-4: -and how water molecules interact with other things like leaves or even you. and adhesion means that water likes to stick to other things. This image shows both cohesion and adhesion at work.
