Capillarity:
Capillarity is the ability of a liquid to flow against gravity in a narrow tube, such as a straw. It is caused by the combination of the liquid's surface tension and the adhesion of the liquid to the sides of the tube.
Viscosity:
Viscosity is a measure of a liquid's resistance to flow. A more viscous liquid is thicker and flows more slowly than a less viscous liquid.
Coefficient of Viscosity:
The coefficient of viscosity is a numerical value that represents the viscosity of a liquid. It is a measure of the liquid's resistance to flow and is used to compare the viscosities of different liquids.
Surface Tension:
- Surface tension is the property of a liquid that causes it to form a slightly rounded surface when it is in a container or on a flat surface.
- This is because the molecules at the surface of the liquid are attracted to each other more strongly than they are to the air above.
Examples:
- -Capillarity: A drinking straw demonstrates capillarity.
- -Viscosity: Honey is more viscous than water and flows more slowly.
- -Surface Tension: A drop of water on a flat surface demonstrates surface tension.
