Everything we know is made up of MATTER.
What is matter?
Anything which has MASS and has a VOLUME is matter.
The particles of matter are so small that it is beyond our imagination. These Particles also have space between them. Apart from this, particles of matter also have a continuous movement called kinetic energy.
The hotter the matter is, the more is the kinetic energy.
The particles have a property of mixing with each other. This is called diffusion and the higher the kinetic energy is higher the diffusion rate will be.
The particles of matter do have space between them they still attract each other.
Where force of attraction is the highest and particles are closely packed, that state is called “solid”. The state where particles are loosely packed and do not have a strong attraction between them is called “liquid”. The state where particles roam freely with least attraction force between them is called “gas”.
SOLIDS: Have definite shape, volume and fixed boundaries. They maintain their shape when subjected to outside force and show negligible compressibility. Solids may break under force and are rigid in nature.
LIQUIDS: Have no definite shape & boundaries but have volume. They take shape of any container they are put into so they are not rigid but are fluid. Solids, liquids and gases all can diffuse inside. Liquids since they have greater space between them. For example, the Oxygen and Carbon dioxide dissolved inside water are essential for the aquatic life. Liquids have higher kinetic energy than solids.
GAS: Has no shape and no definite volume with none of the fixed boundaries. Highly compressible. Has most kinetic energy out of all 3 states. This is the reason, why the smell of hot food reached before entering the kitchen. Because the diffusion rate is highest. Due to free movement of gas particles hit each other and containers walls, exerting a pressure per unit area.
Some of the gases are liquefied to be easily transported. Example: The LPG gas used in kitchen. The CNG gas used in vehicles. These gases are compressed to a point where they change their state to become liquid. This means, matter can change their states.
