MATTER:
Anything which has mass and occupies some space is called matter. For example; graphite, carbon di oxide, mercury etc.
SOLID:
The type of matter which has definite shape and possesses definite volume, is termed as solid. For example; coal, diamond, iron etc.
LIQUID:
The type of matter which possess definite volume and does not possess definite shape, is termed as liquid. For example; water, honey, petrol etc.
GAS:
The type of matter which neither possesses definite volume nor definite shape, is termed as gas. For example; air, Sui gas, ammonia etc.
PLASMA:
In the plasma state, atoms are stripped of their electrons, resulting in a collection of positively charged ions and negatively charged electrons. This separation of charges allows plasma to conduct electricity and respond to magnetic fields. Plasma is often described as a "superheated gas" because it is very hot and can be found in stars, lightning bolts, fluorescent light bulbs, and even some cutting-edge technologies like plasma TVs.
BEC (Bose Einstein Condensate):
Bose-Einstein condensate (BEC) is a fascinating state of matter that occurs at extremely low temperatures, close to absolute zero. In this state, a large number of particles, such as atoms or subatomic particles called bosons, come together and behave as a single entity, like a super atom.
