Question

What do you mean by plasma and Bose-Einstein Condensate?

Answer 1

Hint: These are different types of matters present in the universe. Apart from the three states of matter gas, liquid and solid there are also other types of states of matter.

Complete answer:
Plasma and Bose-Einstein condensate are fourth and fifth states of matter respectively.
Plasma:
As we stated plasma is considered to be fourth states of matter apart from the other three common states of matter. It has hot ionized gas approximately with an equal number of positively and negatively charged electrons. When we consider their characteristics, they are entirely different from the rest of the matters. That is why it is considered as another state of matter. When we take an example of plasma’s properties, we can see that they are made up of electrically charged particles and strongly influenced by electric and magnetic while neutral gases are not. It may not be seen widely in the earth but it is to believe that in the universe everything is made up of plasma.
Bose-Einstein Condensate (BEC):
They are considered as the fifth states of matter after the plasma. They are a group of atoms cooled to within a hair of absolute zero. For example, we can take Helium. They are amazingly cold, too close to ${270}^{\circ }C$ or zero kelvin. BEC when reached near to temperature zero the atoms are hardly moving relative to each other since they have very less free energy to do so. From that point onwards atoms come closer and enter the same energy level. It appears as if they have formed and starts behaving like a single atom.

Note:
Apart from these 5 states of matter there are also other states of matter. But in general, we only talk about only the 4 states of matter as the rest of them are still in experimental processes.
