2. THE FOURTH STATE OF MATTER “ PLASMA” DEFINATION Plasma is an ionized gas made up of positively and negatively charged particles, or ions and electrons, that have roughly equal charge densities.  FORMATION Plasma is created when a gas is heated to a high temperature or exposed to energetic photons, like X-rays or ultraviolet light. This process ionizes the gas, meaning the electrons are ripped away from the atoms

3. THE STATES OF MATTER The five states of matter are solids, liquids, gases, plasma, and Bose-Einstein condensates Solids Have a definite shape and volume, and are resistant to outside forces. Examples include stone, wood, brick, and Ice. Liquids Have a definite volume but no definite shape, and can flow. Examples include milk and water.  Gases Have no definite shape or volume, and are easily compressible. Examples include oxygen and hydrogen
