Question

(b) Comment upon the following:
rigidity, compressibility,
fluidity, filling a gas
container, shape, kinetic
energy and density.​

Answer 1

Answer:1) Rigidity = It is the tendency to maintain the shape whenever outward force is applied. 2) Compressibility = It is the tendency to decrease the volume of the matter by applying force and not changing the mass. 3) Fluidity = It is the tendency of matter to flow.

Explanation:

Answer 2

Rigidity: The condition which do not alters the shape of solids.

Compressibility: Compressing particles of gases

is called compressiblity.

Filling a gas container: In the laboratory, after the preparation of gases, they are collected in gas jar. This is called filling a gas container.

Fludity: Fluidity means flowing of liquids freely.

Shape: Things are in which form is called shape.

Kinetic energy: The energy possessed by moving body is called kinestic energy.

Density: Density is the mass per unit.
