Given information
Water in a glass tube that contains grease or oil residue displays a flat meniscus (left), whereas water in a clean glass tube displays a concave meniscus (right).
Step-by-step explanation
Step 1.
The ability of a liquid to flow upward in tight gaps without the aid of external forces is known as capillary action. Due to the surface tension of the water molecules and intermolecular forces between the water and its surrounding surface, capillary action allows water to travel upward.
The rate at which water rises in a glass tube is influenced by adhesive and cohesive forces. These two forces are totally opposite.
