Phases of Matter VII - Plasmas
Written by Translator on June 27, 2008 – 5:25 pm -Crossposted at http://Dailykos.com
A plasma is a noncondensed, fluid state of matter, much like a gas. The difference between gases and plasmas is that gases are electrically neutral, while plasmas have had some, most, or all (depending on conditions) of its atoms separated from one or more electrons.
Thus, a plasma is mixture of ions (atoms missing one or more electrons) and free electrons. This makes them have some extremely useful properties, and we exploit those properties on a daily basis.

This diary introduces a new series to follow up the one on the electromagnetic spectrum. Compared to light, phases of matter are extremely complex, so we will break the subjects into small chunks for easier assimilation.
