About Plasma It’s confirmed that there are 3 physical forms of material existence in human living environment. They are solids, liquids and gases. And any physical form can exist in different states due to the influence of environmental factors, e.g. liquids can exist as ice under the temperature of 0℃, ice can be melted into liquids at above 0℃, and liquids can be vaporized into steam at above 100℃. It’s tested that under some specific condition, to heat the liquids continually, then the electron of some molecule and atomic in liquids will be separated, thus the electron is ionized. It’s called plasma when material exists under that state. 99% visible materials in universe may exist in plasma state, including fixed stars. Plasma can be natural or man-made. For example, the lightning during rainstorms is plasma phenomena, because the high voltage difference between cloud layer and ground makes the air ionized. And neon light and fluorescent lamp are from man-made plasma. The gases in light tube are ionized into plasma state.
