Question

(a) Define the following properties of matter (i) rigidity (ii) diffusion (iii) compressibility (b) Arrange solids, liquids and gases in the ascending order as regards the extent to which each of the above properties is exhibited them. (c) Write any one example from your daily life experience which is based on diffusion of gases.

Answer 1

1) Rigidity - The property of a metal that it posseses due to its hardness is known as rigidity.

Solid>Liquid>gases
2) Diffusion - Intermixing of particles of two different states of matter is called diffusion.

Gases>Liquid>Solid

3. Compressibility - The ability of a metal by which its volume can be reduced.

Gases>liquid>solid.
