States of Matter

4 States of Matter: Solid 2. Liquid 3. Gas 4. Plasma States of Matter—physical forms in which a substance can exist 4 States of Matter: Solid 2. Liquid 3. Gas 4. Plasma

Solids Particles are very close together (strong attraction) Particles vibrate in place Melting—solid to liquid (energy must be added—particles speed up) Freezing—liquid to solid (energy must be removed—particles slow down)

Liquids Slightly more energized particles than a solid (less attraction between particles) Evaporation (Vaporization)—liquid to gas (energy must be added--particles speed up)

Gas Particles move quickly (lots of energy) Very little attraction between particles Condensation—gas to liquid (energy must removed—particles slow down)

Most energized of all the states Examples: Stars Plasma—super heated gas that contains electrically charged particles (called ions) Most energized of all the states Examples: Stars Auroras (Northern Lights) Certain TVs Lightning Fluorescent lights Neon signs https://www.youtube.com/watch?v=2osF6l6-zWg https://www.youtube.com/watch?v=fVsONlc3OUY http://www.visitnorway.com/us/what-to-do/attractions-culture/nature-attractions/let-there-be-northern-lights/what-are-the-northern-lights/
