We classify the states of matter as solid, liquid and gas. Now, let's examine the fourth state of matter. If you do not hear the name frequently, the most common form of material in the Universe is plasmas. Plasma is the ionization of a gas by energizing it.
Normally, electrons in atoms are bonded to atomic nuclei. The atom acts as a whole. Ionization is the breaking of bonds between electrons and atomic nuclei. In the plasma, ions (electrons broken off) and free electrons move independently of each other. The numbers of positively charged ions and negatively charged electrons are almost the same.
it is known that electrons move around the atomic nucleus. In the gas, the electrons bond to the atomic nucleus. Plasma is usually obtained by heating a gas to the point where electrons have enough energy to get t away from the atomic nucleus. It is composed of charged particles and is therefore affected by electric field and magnetic field. In addition, it transmits electricity well. But most of the gases are insulated. It does not conduct electricity. It can also be obtained using lasers and intense electromagnetic fields.
Properties Of The Plasma
-
It is composed of charged particles and is therefore affected by electric field and magnetic field. And in addition, it transmits electricity well. But most of the gases are insulated. It does not conduct electricity.
-
Just like gases, it does not have a specific shape and volume.
-
In this case the chemical reaction takes place faster than in the gaseous state.
-
The ions and electrons in the plasma can create magnetic fields as they move.
-
They can be confined within the magnetic field. In nuclear fusion research, scientists can control plasmas at millions of degrees using magnetic fields.
-
When exposed to a magnetic field, it may form filiform or layered shapes.
Origin Of ‘Plasma’
The plasma word is in Greek, "gel" or "material that can be shaped".
In 1879, Sir William Crookes became the first scientist to notice the "light-emitting substance" he saw in the Crookes cathode ray tube experiment. British physicist Sir J.J. Thomson's experiments with a cathode tube have suggested an atomic model that claims that the atom consists of plus and minus charged particles. This was first used in 1928 by chemist Irving Langmuir, and in 1932 he received the Nobel Prize for Chemistry.
