Question

Define the following terms :-
I) Rigidity
II)Compressibility
III)Diffusion

Answer 1

rigidity means - a thing that maintains it\'s volume and shape for e.g - solids.And Compressibility is the change in the volume of a substance (e.g. gases) as response to the pressure change.AND Diffusion is the movement of particles from the region of high concentration to the region of low concentration. Only gases andliquids have the ability to diffuse.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.

Answer 2

Rigidity is the property of a solid body to resist deformity.
Compressibility is the measure of relative volume ,change of a fluid or solid as a response to pressure change.
Diffusion is the movement of particles from region of high concentration to region of low concentration.Only gases and liquids have the ability to diffuse.
