Solid:- i) Particeles are very close to each other.

ii) The forse of attraection between the particles are very strong.

iii) the spacee betwwen the particles is very less.

iv) The strong force between the particles donot allow them to move freely.

v) Solids have definite volume and shape.

Liquid :- i) Particles are not so closely packed like solid substances but closer than
gasious substances.

ii) The force of attraction betwwwn the particles are not so strong like solid.

iii) The distances between the particles is bigger than solids but lss than gases.

Iv) They can flow.

v) They have definite volume but do not have definite shape.

vi) They take the shape of the container in which theey have kept.

Gas :- i) Particles are very far from each other.

ii) The force of attraction of attraction is least in gas.

iii) The distance between the particles are highest in comparison to solids and liquids.

v) They can flow easily.

vi)They do not have definite volume or shape. They take the shape and volume of the
container.
