Step-by-step explanation:
Anything that occupies space and has mass is called matter.
(a) Inter particle space
- Solids - Atoms of a solid substance are closely packed with each other due to which there is very less or no inter particle space.
- Liquids - Atoms of a liquid are little loosely packed due to which there is some inter particle space.
- Gases - Atoms of a gas are very loosely packed due to which there is large inter particle space.
(b) Inter particle force of attraction
- Solids - Atoms of a solid are attached to each other by strong force of attraction.
- Liquids - Atoms of a liquid have slightly less force of attraction as compared to a solid substance.
- Gases - Atoms of a gas have Vander waal forces. Hence, there is no inter particle force of attraction between atoms of a gas.
(c) Particle motion
- Solids - There is low or negligible particle motion between atoms of a solid.
- Liquids - There is high particle motion as compared to that present in a solid.
- Gases - There is very high particle motion as compared to solids and liquids.
