Question

What is the reason for the existence of the three states of matter?

Answer 1

Explanation:

• There are three states of matter: solid; liquid and gas.
• The three states of matter differ with respect to the inter particles spaces. These are minimum in the solid state while maximum in the gaseous state.
• The three states of matter exist due to the difference in the inter molecular force of attraction between the molecules of the substance.
• When the intermolecular force of attraction is strong and molecules are closely bound, then the matter exists as solid.
• When the intermolecular forces of attraction is weak and molecules are less closely packed, then the matter exists as liquids.
• When the intermolecular force of attraction are very weak and molecules are free to roam, then the matter exists as gas.
