Question

11) Comment upon the following properties:-i. Rigidity ii. Compressibility iii. Fluidity iv. Kinetic energy

Answer 1

Rigidity = The property of matter which do not allow it to change its shape and size.

Compressibility= The property of matter which allows it to change shape by some force applied.

Fluidity= The property of matter to flow.

Kinetic energy= Energy possessed by moving particles by the virtue of their motion.

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.
