Matter occurs in four states: solids, liquids, gases, and plasma. Often the States of Matter States of Matter of a substance may be changed by adding or removing heat energy from it. For example, the addition of heat can melt ice into liquid water and turn water into steam.
- States of Matter can exist in one of three main states:States of Matter,States of Matter, or States of Matter
- Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around.
- Liquid matter is made of more loosely packed particles. It will take the shape of its container. Particles can move about within a liquid, but they are packed densely enough that States of Matter is maintained.
- Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume. A gas can be compressed.
Difference between Solid, Liquid and Gas
Defination: Solid refers to a form of matter which has structural rigidity and has a firm shape which cannot be changed easily.

- Close packing: Particles are very closely packed.
- Shape and Volume: Fixed shape and volume.
- Energy: Lowest
- Compressibility: Difficult
- Arrangement of molecules: Regular and closely arranged.
- Fluidity: Cannot flow
- Force of attraction among particles: Strongest
- Sound speed: Fastest
- Storage: Don’t need container for storage.
- Defination: Liquid is a substance, that flows freely, having a definite volume but no permanent shape.
- Close packing: Less closely packed, interparticle distance more than solids but less than gases
- Shape and Volume: No fixed shape but has volume.
- Energy: Medium
- Compressibility: Nearly difficult
- Arrangement of molecules: Random and little sparsely arranged.
- Fluidity: Flows from higher to lower level
- Force of attraction among particles: Weaker than solids but stronger than gases
- Sound speed: Faster than gas but slower than solid
- Storage: Cannot be stored without container.
- Defination: Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in
- Close packing: Very loosely packed, particles are free to move with maximum interparticle distance.
- Shape and Volume: Neither definite shape nor volume
- Energy: Highest
- Compressibility: Highly compressible
- Arrangement of molecules: Random and more sparsely arranged
- Fluidity: Flows in all directions.
- Force of attraction among particles: Weakest
- Sound speed: Lowest among all
- Storage: Needs closed container for storage.
