The fourth fundemental state of matter. (Plasma)

Plasma created by Jacobs Ladder
Hey everybody. I'll tell you that I'm just 13 years old . I have been studying Physics, Biology and Chemistry for four years. In these four years I have only learned about three fundamental states of matter before but not four. Ah I remembered, I've learned it before but I forgot it. Lots of people and scientists forget the existence of plasma. Plasma eh. Plasma from the Greek word πλάσμα, meaning anything formed. Plasma  is one of the four fundamental states of matter the others being solid, liquid, and gas. Heating a gas may ionize its molecules or atoms reducing or increasing the number of electrons in them, turning it into a plasma, which contains charged particles like positive ions and negative electrons or ions. Ionization can be induced by other means, such as strong electromagnetic field applied with a laser or microwave generator, and is accompanied by the dissociation of molecular bonds, if present. Plasma is so conductive that it is more powerful conductor than a solid superconductor like yttrium oxide, it so conductive that it can be treated virtually infinite. Like gas, plasma does not have a definite shape or a definite volume unless enclosed in a container; unlike gas, under the influence of a magnetic field, it may form structures such as filaments, beams and double layers. To turn water solid, we'd cool it but to turn gas into plasma ,we'd had to ionize it. Plasma can be artificially created by using the Jacobs ladder to produce plasma. That's for today everyone.
