  1. Plasma The Fourth Property of Matter. Sungjae Cho, Douglass Cook

  2. What is Plasma? • A mixture of molecules and free radicals or charged ions • An element with a very high amount of energy. • Contains charged particles, positive ions and negative electrons

  3. Characteristics of plama • can only be seen under certain circumstances, like in a plasma ball. • It's not a solid nor is it a liquid. It's SOMEWHAT of a gas, but it's partionally ionized

  4. How is it formed? • 1. Heating a gas dissociates its molecular bonds, rendering it into its constituent atoms. 2. Further heating leads to ionization (a loss or gain of electrons), turning it into a plasma. containing charged particles, positive ions and negative electrons

  5. Where can it be found? • Most flames • Lightning • All the stars, and even the space between the stars is filled with a plasmaThe solar wind

  6. Why plasma? • the most populat phase of matter. • Most of the matter in the universe exists as plasma. • Electrons in metals exist as a plasma. • Ions in our ionosphere exist as a plasma. • Without plasma, the earth would have never existed.

  7. How can it be used? • plasma displays, including TVs • Inside fluorescent lamps (low energy lighting), neon signs • Rocket exhaust and ion thrusters • Fusion energy research • can be inoculated with other chemicals to detectthe body's reaction to infections, cancer, or HIV, the virus that causes AIDS
