➡️ What is Matter?
↪️ Anything that has mass, occupies space and can be perceived by our senses is called matter. Thus, the air we breathe is also made of matter. Matter exists in three states solid, liquid and gas.
Answer :
The term matter stands for anything that has mass and occupies space. Anything in this universe that has these properties can be called matter. Matter can be very small (an atom) and can be very large too (a tree, house, etc).
The word matter is sometimes used to refer a pure substance also.
★ Types/forms of matter :
There are four main natural states of matter : Solid, liquid, gas & plasma.
- Solid : In solid state, the particles of matter are tightly packed. They have a fixed position and does not change their shape. Solids have high denisty, definite shape, mass & volume. They are resistant to pressure due to which they break when excessive force is applied. Examples are - chair, car, table etc.
- Liquid : In liquid state, the particles of matter are nit tightly packed, they are loosened. Hence, liquids do not have a definite shape. They constantly take the shape of the container in which they are kept. They flow and change shape. Examples are - water, petrol, kerosene etc.
- Gases : In gaseous state, particles of matter are in constant motion. Gases have a large amount of space between its its particles. They do not have a definite shape or volume. They also have a high kinetic energy. Examples are - oxygen, hydrogen, etc.
- Plasma : Plasma is a rare form of matter here on earth, but it's abundant in the universe. The sun and all other stars are made of plasma. They contain highly charged particles with an extreme kinetic energy. Plasma is often made using gases like neon, krypton, etc.
★ Some other forms of matter :
Apart from these four natural states. Scientists have discovered and created many other forms of matter. Some of them are :
➪ Rydberg polaron
➪ Quantum spin liquid
➪ Fermionic condensate
➪ Bose–Einstein condensate
➪ Electron-degenerate matter
