Question

Differentiate between solid, liquid and gas.​

Answer 1

Solids

• Solids have definite shape, volume and size.
• It's so because the intermolecular space between the molecules in solids is negligible and the intermolecular force of attraction is high in Solids.
• Solids are rigid.
• Compressibility is negligible in solids.

Liquids

• Liquids have a definite volume, but indefinite shape and size.
• Intermolecular space between the molecules in liquids is more than solids and inter molecular force of attraction is low in liquids as compared to solids.
• Liquids can be compressed.

Gases

• Gases neither have a definite volume, nor they have a definite shape and size.
• Intermolecular space between the molecules in gases is highest as compared to solids and liquids.
• Intermolecular force is negligible in gases.
• Gases can be compressed easily.
