Question

Discuss the three states of matter: solid, liquid and gas on the basis of molecular model.

Answer 1

• In solid form molecules are so tightly packed that there is vey less intermolecular space and there is high intermolecular force of attraction.
• In liquid form molecules are less tightly packed as compared to solids and also there is less force of intermolecular attraction.
• In gaseous form molecules are far apart from each other, so they have the greatest intermolecular distance which results in the weakest intermolecular force of attraction.
