Solids are hard and rigid

• because the molecules in it are loosely packed

• because the molecules in it are very tightly packed

• because there are no molecules in it

• because the molecules are spread out with lot of space

Liquids are free flowing

• because the molecules in it are tightly packed

• because the particles are very small

• because the molecules are very less

• because the molecules in it are loosely packed

Gas is spread out because

• it has a definite shape

• molecules in it move freely

• molecules in it are tightly packed

• there are no molecules in it
