Question

What's the difference between solid liquid and gas ?

Answer 1

solid-in this the molecules are tightly packed.usually solids are hard but sometimes they are soft also.
liquids-in liquids the molecules are loosely packed and have space between them.liquids can flow from higher level to lower level.
gas-gas have their molecules far apart and have lots of space in between them

Answer 2

Solid: 1. large intermolecular force.
 2. very less intermolecular space.
3. high density.

liquid: 1. weak intermolecular force.
2. large intermolecular space.
3. density is low.

gas: 1. Very weak intermolecular force.
2. very large intermolecular space.
3. very low density.
