We explain what the plasma state is and some of its properties. In addition, the types of plasma that exist and examples.
What is the plasma or plasma state?
One of the four states of aggregation of matter, together with the liquid, solid and gaseous, is known as `` plasmalasm '' or `` plasmatic state ''. When we talk about a substance in this state, we refer specifically to an ionized gas, or in other words, to a gas of which volumes have been stripped of part of their original electrons, and have been electrically charged (they do not have electromagnetic balance).
This means that the plasmatic state is, in principle, similar to the gas, but with very different properties of those of a cold gas . Among them are the `` trend '' of the `` plasma '' to conduct electricity effectively, or its great response to the magnetic fields.
The `` plasma '' is not a frequent state in everyday life.It can be obtained through a process of ionization of gases, as simple sometimes as heating them to make their particles vibrate more quickly. Other means for this are magnetization and the application of electricity, and other artificial processes.
Likewise, it can be done at a plasma to return to a gaseous state, through a process, any of the deionization: for example, Remove the substance from the substance and allow its particles to recover its lost electrons, gaining stability and becoming a gas again. .
There are two known types of plasma:
- It is cold, the most harmless to living beings, since it does not cause burns, and it is not harmful, because its particles do not move so quickly as they do, instead, their electrons.
- Plasma hot, whose tomos are colliding with each other T move and lose electrons, generating in the process varying amounts of Light and caloric energy.
It can serve you: Gaseous State.
Examples of plasma or plasma state
Some examples of matter in plasma state are:
- The sun The king star is a large ball of gases in perpetual reaction, whose reactions are so violent and gravity so massive that its particles are compressed and reach the plasma state.
- The fire . It has never been easy to answer what fire is, that flame capable of generating light and heat: it is a hot plasma.
- Plasma lamps . The so-called "plasma balls" or "plasma spheres" are decorative or playful devices invented by Nicola Tesla in his experiments with high frequency electricity. It is nothing more than a mixture of low pressure gases in a transparent container, into which high frequency and high voltage electricity is injected, achieving an electric field.
- Neon lights The very frequent neon lamps or bulbs use this element (a noble gas) to achieve a bright and cold plasma, which is quite safe, not very reactive (since it is neon) and very functional.
- Lightning bolts Fast and very hot (27, 000 ° C) lightning bolts are forms of plasma that arise in the atmosphere, when the gases in it are electrically charged during the hydrological cycle, and thus generate a decompensation of the electromagnetic field, which through a discharge violent tries to restore the balance.
