Question
How many states of matter have been determined by scientists so far?
Answer (Detailed Solution Below)
The correct answer is 2
There are 5 states of matter determined by scientists so far:
Solids, Liquids, Gases, Plasma and Bose-Einstein condensate.
Solids: Solids have fixed shape and fixed volume. Solids have high density. Solids are negligibly compressed. Particles have maximum force of attraction. Solids have the least intermolecular space between particles.
Liquids:In liquid, particles are less tightly packed as compared to solids. That is why there is less force of attraction than solids. They take the shape in which container it is placed. For example: Milk, blood, coffee, etc. There are weak forces of attraction between them.
Gases: In gases, particles have a large space between them. That is why, force of attraction between the particles is negligible in gases and they can move freely. It can be highly compressed. For example: oxygen, carbon-dioxide, nitrogen, etc.
Plasma: Plasma is an ionised gas. It has equal numbers of positively charged ions and negatively charged electrons. A spark in a gas creates plasma. For example: plasma in the form of stars glows.
Bose-Einstein condensate: Bose-Einstein condensate exceptional state of matter. The group of particles going in the same direction at the same speed. This happens in the Bose-Einstein Condensate. These particles are known as Bosons.
