Is Fire a solid, liquid or gas?
As we know that there is only 3 states of matter i.e, SOLID, LIQUID and GAS. But we cannot consider it in either of it. But the fire,
And on a scientific level, fire differs from gas because gases can exist in the same state indefinitely while fires always burn out eventually.
So a new state came into EXISTENCE considered as PLASMA. Hence fire comes under PLASMA [ 4th state of matter].
PLASMA:-
Plasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas. Just as a liquid will boil, changing into a gas when energy is added, heating a gas will form a plasma – a soup of positively charged particles (ions) and negatively charged particles (electrons).
EXAMPLES
Neon signs and lightning are examples of partially ionized plasmas. The Earth's ionosphere is plasma and the magnetosphere contains plasma in the Earth's surrounding space environment. The interior of the Sun is an example of fully ionized plasma, along with the solar corona and stars.
It is also used in making TELEVISION, NEON SIGNS etc.
Bose-Einstein condensates:-

Bose-Einstein condensates were first predicted theoretically by Satyendra Nath Bose (1894-1974), an Indian physicist who also discovered the subatomic particle named for him, the boson. Bose was working on statistical problems in quantum mechanics and sent his ideas to Albert Einstein.
It is a group of atoms cooled to within a hair of absolute zero. When they reach that temperature the atoms are hardly moving relative to each other; they have almost no free energy to do so. At that point, the atoms begin to clump together and enter the same energy states.
Building on his calculations, Albert Einstein predicted a new state of matter – the Bose-Einstein Condensate (BEC).
BEC is formed by cooling a gas of extremely low density.
