- Every solid matter has definite volume and shape. Because inter particle attractions between particles is maximum.
- Solids are highly rigid. Because the space between the particles of a solid are negligible.
- A solid matter cannot flow. Because the particles of solids have least kinetic energy.
- Solids have highest density because of negligible gap between particles.
- Solids are almost incompressible. Due to negligible gap between particles.
- A solid can have any number of surfaces.
- Solids don’t apply any pressure.
- Every liquid substances has definite volume but not a definite shape. They can take the shape of container in which they are poured. Liquids have no definite shape because inter molecular space between molecules of a liquid is less compared to solids.
- Liquids are less rigid compared to solids. Because the inter molecular space between the molecules of a liquid is higher compared to solids.
- Since the inter molecular force is less for liquids thus a liquid can flow in which they are stored.
- Liquids have less density compared to solids because of greater gaps between molecules.
- Liquids are more compressible than solids. Because the molecules are loosely packed.
- A liquid can have only one upper surface.
- Liquids apply pressure on the walls of their containers. But this pressure is less than the pressure applied by gases.
- A gas has neither a definite volume nor a definite shape. The volume of a gas is the volume of the container in which it is stored. And its shape is the shape of the container. Because inter molecular force is negligible and inter molecular space is highest.
- Gases are not rigid at all. Because the molecules of a gas are free to go anywhere.
- Gases can flow in all directions. Because they have almost zero molecular force among their molecules.
- Gases have the least density among all kinds of matters.
- Every Gas is highly compressible because of having highest molecular spaces among molecules.
- Gases have no surfaces.
- Gases apply the highest pressure on the wall of its containers.
