(a) Tabulate the differences in the characteristics of states of matter.

(b) Comment upon the following: rigidity, compressibility, fluidity, filling a gas container, shape, kinetic energy and density.

 

Answer

 

Solid

Liquid

Gas

Rigidity

They are rigid at room temperature.

They are not rigid.

They are not rigid.

Compressibility

They can not be compressed.

They can be compressed.

They can be compressed very easily.

Fluidity

They can not flow.

They can flow.

They can flow.

Filling a gas container

They have a definite shape and volume, so they do not fill a gas container completely.

They have a definite volume, so they do not fill a gas container completely.

They have no definite shape and volume, so they fill a gas container completely.

Shape

Have definite shape and volume.

Have a definite volume but not a definite shape.

Have no definite shape and volume.

Kinetic energy 

Their particles have very less kinetic energy.

Their particles have some kinetic energy.

Their particles have large kinetic energy.

Density

They have high density.

They have less density than solids but higher than gases.

They have the least density.
