Question

Comments upon the following:rigidity,comprehensibility,fluidity,filling agas container,shape,kinetic energy and density of various states of matter.

Answer 1

i) Rigidity: The tenndency of a substance to retain / maintain their shape when subjected to outside force.
ii) Fluidity: The tendency of particles to flow is called fluidity. Liqiud ans gases flow.
iii) Shape: Solid have maximum intermolecular force and definite shape. Whereas liquids and gases takes the shape of container.
iv) Kinetic energy: The energy possessed by particles due to their motions is called kinetic energy.
v) Density: It is defined as mass per unit volume.

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.
