Question

define matter and its states.

Answer 1

Matter is a substance having mass and occupy space.Matter has different sizes,mass and molecules.

There are five states of matter-:

Liquid-A state of matter in which molecules are not too closed to each other but they have spaces between them.

Solid-A state of matter in which molecules are tightly packed to each other and does'nt have spaces between them.Thus it's very hard to break a solid.

Gas-A state of matter in which the molecules are very loose and have a lot of space between them.

Plasma-This is hot ionized gas and has positively charged ions.

Boss Einstein is the fifth state of matter,its dilute gas of bosons.

Answer 2

Everything around us which occupy space and contain mass is called matter.

there are five states of matter basically there are three states of matter.

1). Solid state :- the objects which have definite shape, volume, distinct boundaries and have negligible compressibility are classified into solid state.

for example :- pen, wood, iron etc.

2). Liquid state :- the objects which do not have fixed volume are put under liquid state.

for example:- water, milk, oil etc.

3). Gaseous state:- The objects which do not have fixed shape or fixed volume are classified under gaseous state.

for example:- Air, nitrogen, LPG, CNG etc.

4) Plasma state :-  Plasma is an ionized gas. plasma like gases have undefined shape and indefinite volume.

for example :- Ionized gas

5).  Bose–Einstein condensate (BEC) :- A BEC is a state of matter that can arise at very low temperature. BEC atoms are closer than the atoms of solid.

For example :-  cold liquid helium
