Question

Compare the arrangement of molecules in solids, liquids, and gases?

Answer 1

Solid, liquid, and gas are three states of matter.

Solid:

• Solids are very hard and rigid.
• Solids have a definite shape and definite volume.
• The intermolecular force of attraction between molecules in solids is very strong and molecules are very closely packed to each other.
• So, the molecules in solids hardly move from their place.

Liquid:

• liquids have a definite volume but not a definite shape.
• The intermolecular forces of attraction in the liquids are not so strong as in solids because there is space between the molecules. This means molecules are less closely packed to each other.
• The molecules in liquid can move from one place to another and this property of liquid is called fluidity.

Gas:

• Gases neither have definite shape nor definite volume.
• The intermolecular force of attraction between the molecule is negligible as compared to solids and liquid because the molecules are very far away from each other.
• Due to the large space between the molecules, the molecules are free to move.
