(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.
a.
Compressibility: Compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
Rigidity:Rigidity is the property of a solid body to resist deformation.
Diffusion is the movement of particles from the region of high concentration to the region of low concentration. Only gases and liquids have the ability to diffuse.
b.
Compressibility:
Gas< liquid<gas
Rigidity
Solid>liquid>gas
Diffusion:
Gas>liquid>solid
c.
When you open a bottle of perfume, its fragrance spread in the entire room due to diffusion. It is due to diffusion plant absorbs and transports water from one region to another.
