Question

Differentiate between solids, liquids and gases on the basis of:
a)Density
b)Kinetic energy of particles
c) Rate of diffusion

Answer 1

solid:-

• Density:-. they have high density.
• Energy:- their particles have minimum energy.
• Diffusion:- they normally do not show the property of diffusion although some rare example of diffusion of one solid into another are known

liquid:-

• Density:- their density is lower than solid but much Higher than gases.
• Energy:- their particles have energy higher than solid.
• Diffusion:- they show the property of diffusion. as a result, solid, liquid and gases all can diffuse in liquids.

Gas:-

• Density:- they generally have very low densities.
• Energy:- their particles have highest energy.
• Diffusion:- they diffuse very rapidly. the rate of diffusion of a gas is, however, inversely proportional to the square root of its density. thus, liquid, gas diffuses more rapidly than the heavier one.
