We know that matter can present itself in solid states, liquid and gas. Nonetheless, there is a state called plasma, also known as the fourth state of matter.
For an overview of how plasma is produced, water can be taken as an example.
Considering the three physical states of matter, solid, liquid and gas, there is ice, the water and steam. The basic difference between these three states is how much energy is in each of them.. If we add energy in the form of heat to the ice, he turns into water. And if we add more energy to this water, she will turn to steam, splitting into two gases: hydrogen and oxygen.
If you continue to add energy to the steam, some of its properties are changed, such as temperature and electrical characteristics. This process is called ionization., and when that happens the gases become plasma.
Plasma is an electrical conductor, and the smaller the place where he is, the higher your temperature. To better understand how this happens, Let's take an example of an electric current flowing through a wire.. If we narrow the wire through which the electric current passes, resistance to current flow increases, increasing the voltage between the electrons and, consequently, the wire temperature.
