Plasma - The 4th state of matter

What is plasma? The 4th state of matter

We know the basic 3 states of matter; solid, liquid and gas.
Lets consider solid, if we give more energy to solid (example by heating) it became liquid. If we give more energy to liquid it become gas, example water.
But what will happen if we heat the gas?
In gaseous state molecules and element are not in ionized form.
When we heat the gas, above certain temperature the electrons get removed from the atom, we will get ionized gaseous state which is plasma.
Plasma is a gas of ions – atoms or molecules which have one or more orbital electrons stripped (or, rarely, an extra electron attached), and free electrons.
Plasma makes 99% of visible universe.
In 1879 Sir William Crookes first discovered plasma in laboratory.
Irving Langmuir coined the term plasma, because it looked like blood plasma.
Plasma is very energetic and emit light.
Plasma can be created artificially by knocking of electrons from atoms which can be done by heating a neutral gas and by subjected it to electromagnetic field.
Gas is not a good conductor of electricity, but plasma is a good conductor of electricity, example lightening.
Cold plasma is also formed which we can touch.
Plasma is ionized gas, so it will have more free electron, so it have electric field with it. And magnetic field always accompany electric field.
Plasma is very responsive to mangetic field.
We can store or confine plasma in a spot by using magnetic field.

Plasma is all around us every where.
