| Answer» 30,000°A plasma is a gas, but it is an unusual kind of gas. In a normal gas, the atoms or molecules are electrically neutral, but in a plasma at least some of these particles have either lost or gained an electron, so that a plasma consists of free electrons and positively or negatively charged atoms and molecules known as ions. A high temperature must be reached before a normal gas can be transformed into a plasma. The lowest temperature at which plasma can usually be seen is a few tens of thousands of degrees, but many plasmas are much hotter than this. Plasmas can reach temperatures of hundreds of thousands or even millions of degrees. Relatively cool plasmas usually have a distinctive luminous colour that depends on the gas in which the plasma is formed. | |
