- Heat it up a bit and you'll get a liquid (water). Heat it up a bit more and, pretty soon, you'll have a gas (steam). The more heat you supply, the more energy you inject. The more energetically the molecules (or atoms) have, the further apart they can push and the more they move about.

Mar 19, 2002 · The basic idea of a plasma display is to illuminate tiny, colored fluorescent lights to form an image. Each pixel is made up of three fluorescent lights -- a red light, a green light and a blue light.
The way plasma displays work is similar to how a florescent light bulb works, gas is used to excited phosphors which produce visible light. In plasma displays a voltage is given to the gas within the cells and the gas becomes ionized, creating plasma.

Depending on their power, plasma-cutting torches operate at very high temperatures between 5,000 and 10,000°C. Cold or non-thermal plasma is less well ionised, and although the electrons are high temperature, the positive ions and neutral particles are at a lower temperature.
