2. Solid Has a stable, definite shape Has a definite volume Particles are packed closely together Cannot move freely, can only vibrate Energy and temperature are very low Can only change their shape by force

3. Solid www.nasa.gov/.../auroras/sun_earth_connect.html

4. Liquid Does not have a definite shape Shape is determined by the container in which it is held Volume is definite Particles are farther apart than in solids, and can slide past each other easily Energy and temperature, in comparison to a solid, are higher

5. Liquid www.nasa.gov/.../auroras/sun_earth_connect.html

6. Gas Has an indefinite, unstable shape Volume is determined by the container that is closely sealed Particles are far apart from each other, and can move around quickly Energy and temperature are the higher than those of both solids and liquids

7. Gas www.nasa.gov/.../auroras/sun_earth_connect.html

8. Plasma Hotter than gas A plasma occurs when the temperature is between 1000 degrees C and 1,000,000,000 degrees C Charged particles, usually in equal numbers, such as ions and electron

10. Bose-EinsteinCondensate Colder than solids Occur at temperatures near absolute 0 ((0 K, −273.15 °C, or −459 °F ) Many atoms collapse into the lowest quantum state
