* * * * Heat is molecular motion The higher the heat in a substance the more rapidly its atoms or molecules are “vibrating” As we add heat molecular motion increases Conversely as molecular motion increases things get hotter Illustration: In a microwave we are accelerating the motion of water molecules to make whatever they are in hotter * By now you can probably surmise that to convert a gas to a plasma…….add energy in the form of heat……when the gas reaches a certain temperature it becomes ionized. When a gas becomes ionized it’s structure changes, causing this ionized gas to be a conductor of electricity. This electrically conductive ionized gas becomes the carrier of electrical energy that we produce with our plasma cutting power supplies. If we superheat steam, it breaks down into a mixture of hydrogen (H) atoms, oxygen (O) atoms, positive and negative ions, and free electrons, through a process called “ionization”. This extremely hot, ionized gas is called plasma—the fourth state of matter. * By now you can probably surmise that to convert a gas to a plasma…….add energy in the form of heat……when the gas reaches a certain temperature it becomes ionized.
