Question

describe different state of matter

Answer 1

Different states of matter :

There are three states of matter -

(a) Solid

(b) Liquid

(c) Gas

1) Solid -

✰ On the basis of volume and shape -

=> Solids have definite shape and volume. It can't be changed by compressing or exerting a small amount of force.

✰ On the basis of arrangement of partials -

=> Partials of solids are very tightly packed and they are so rigid.

✰ On the basis of force of attraction -

=> The force of attraction is very high in solid that the particles and molecules of solid cannot move apart from each other .

✰ On the basis of kinetic energy -

=> In case of solid kinetic energy is very low that is why the force of attraction is very high and particles are very tightly packed in solids .

✰ On the basis of diffusion -

=> The rate of diffusion is very low and slow in case of solids that even the particles of a particular thing can take months and years to diffuse completely in solids .

2) Liquids :

✰ On the basis of volume and shape -

=> Liquids have a definite volume but not a fixed shape . Example : If we transfer a liquid from one container to another it will take the shape of another container but the volume of water will remain same .

✰ On the basis of arrangement of partials -

=> The particles of liquids are loosely packed and are fluid as compared to solids .

✰ On the basis of force of attraction -

=> The force of attraction is moderate in case of liquids that is why the particles of liquids can move apart from each other but in a limit .

✰ On the basis of kinetic energy -

=> In case of liquids kinetic energy is moderate that is why the particles and molecules of liquid can move .

✰ On the basis of diffusion -

=> The the rate of diffusion is also moderate in liquids . The particles of a particular object takes only few minutes to diffuse in liquid .

3) Gases :

✰ On the basis of volume and shape -

=>The gaseous state of matter has neither a definite volume nor a definite shape .

✰ On the basis of arrangement of partials -

=> The particles in the gaseous state of matter are very loosely packed and is very much fluid .

✰ On the basis of force of attraction -

=> The force of attraction is very much low in case of gas that is why the particles and the molecules of gas keeps moving far away from each other.

✰ On the basis of kinetic energy -

=> Kinetic energy is very low in case of gas that is why the particles of gaseous state of matter is very loosely packed and very fluid.

✰ On the basis of diffusion -

=> The rate of diffusion is very high in gas that is why if we spray anything like perfumes in in air we are able to feel it smell even sitting several metres away .

Answer 2

$\underline\bold{State\:of\:Matter:-}$

Solid, liquid, gas , plasma and bose-einsten Condensate.

$\huge\bold{Solid:-}$

Solid have definite shape and size. They have high density. Diffusion rate is least in solids. They are rigid and don't flow. They are not compressible. The intermolecular force of attraction between the particles of solid is very strong. For example:- Chair, stone, etc.

$\huge\bold{Gas:-}$

Gas do not have definite shape and size. They have least density. Rate of diffusion is very high. They have the tendency to flow. They are highly compressible.The intermolecular force of attraction between the particles of gas is negligible. Example:- Carbon dioxide, oxygen etc.

$\huge\bold{Liquid:-}$

They do not have definite shape and size. The density is less than solids. Show less diffusion. They have tendency to flow. They are less compressible. The intermolecular force of attraction between the particles of liquid is weak.Example:- Water, milk etc.

$\huge\bold{Plasma:-}$

It consist of super energetic and super excited particles. These particles are in the form of ionised gas. The sun and stars glow because of the presence of plasma.

$\huge\bold{Bose-Einsten\:Condensate:-}$

It is formed by cooling a gas of extremely low density about one-hundered-thousandth the density of normal air to super low temperature.
