Question

defination of matter in long​

Answer 1

Answer: In science, matter is the term for any type of material. Matter is anything that has mass and takes up space.

please mark as brainliest

Answer 2

Anything which occupies space and has mass is called matter.

Example : Air and water, hydrogen and oxygen,sugar and sand etc.

There are three states of matter :-

• Solid
• Liquid
• Gas

Solid : In solids,the particles are closely packed.There is a strong force of attraction between the particles of a solid which holds them together in fixed positions. Thus, the positions of particles in a solid are fixed.

$\sf \green{Properties \: of \: solids}$

• Solids have a fixed shape and a fixed volume.
• Solids cannot be compressed much.
• Solids have high densities. They are heavy.
• Solids don't fill thier container completely.
• Solids do not flow.

Liquids : In liquids, the particles are close together,but they are not as close as in solids.In fact, the particles are somewhat loosely packed in liquids.The spaces between the particles of a liquid are slightly more than that in a solid but they are still very small.

$\sf \green{Properties \: of \: liquid}$

• Liquids have a fixed volume but they have no fixed space. Liquids take tge shape of the vessel in which they are placed.
• Like solids, liquids cannot be compressed much.
• Liquids have moderate to high densities. They are ususlly less dense than solids.
• Liquids don not fill their container completely.
• Liquids generally flow easily.

Gas : In gases,the particles are much farther apart from one another as compared to solids and liquids. The spaces between the particles of a gas are very large.The force of attraction between the particles of a gas is negligible.

$\sf \green{Properties \: of \: Gas}$

• Gases have neither fixed shape nor a fixed volume.Gas acquire the shape and volume of the vessel they are kept.
• Gases can be compressed easily.
• Gases have very low densities.
• Gases fill thier container completely.
• Gases flow easily.

• Plasma
• BEC [ Bose - Einstein Condensate ]
