Question

Discuss the properties of solids, liquids and gases in terms of:

i. Intermolecular forces

Answer 1

Intermolecular forces :

• The molecules in solids are closely packed or tightly packed because of the strong intermolecular force of attraction present between them.
• As the intermolecular force is greater in the case of solids, they have the least intermolecular space present between them.
• In the case of liquids, there is the less intermolecular force of attraction present between them as compared to solids.
• Due to less intermolecular force of attraction present in liquids, they are able to move freely as compared to solids.
• Gas molecules are far apart from each other due less intermolecular force of attraction and greater intermolecular space present between them.
• As they are far apart from each other, they have a greater amount of freedom.
