Question

What is a meniscus ?

What is surface tension ?

​

Answer 1

Answer:

Hiii mate here is ur answer ❤❤

Explanation:

The meniscus is a C-shaped piece of soft and fibrous cartilage, also known as fibrocartilage, that provides shock absorption and cushion to your knee

the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.

Answer 2

Answer:

Meniscus:--A meniscus occurs because of surface tension in the liquid and must be read at eye level. For a concave meniscus, the correct volume will be read at the bottom of the curve. For a convex meniscus, the opposite is true and the correct reading will be at the top of the curve.

Surface tension:--The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. The molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface.

OR

Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid.Surface tension forces are due to intermolecular forces between the liquid's molecules at the liquid's outer boundaries.
