2. Gas Liquid Solid Plasma Bose-Einstein

3. Gas has no definite volume or shape. Gas will expand indefinitely Low density causes even distribution of gasses in containers Gas

4. Definite volume but can change by flowing Molecules touch but are able to move around Liquids take the shape of their container

5.  Definite shape and volume  Tightly packed atoms  They are ridged

6.  Ionic solids- Contain ionic bonds and have definite melting points.  Covalent Solids- There is free electron movement between the atoms.  Molecular Solids-Made up of repeating units of molecules.  Metallic Solids- The valence electrons can jump from atom to atom.  Amorphous Solids- Exist in either rubbery or glassy state.

7.  Plasma is an ionized gas, a gas into which sufficient energy is provided to free electrons from atoms or molecules and to allow both species, ions and electrons, to coexist.  In effect a plasma is a cloud of protons, neutrons, and electrons where the electrons have come loose from their respective atoms and molecules, giving the plasma the ability to act as a whole rather than a bunch of atoms

8. Plasmas are the most common state of matter in the universe composing more than 99% of our visible universe and most of that not visible. Plasma occurs naturally and makes up the matter of our sun, the core of stars and occurs in quasars, x-ray beam emitting pulsars, and super novas. Most space plasmas have low density, for example the solar wind averages only 10 particles per cubic cm.

9. The collapse of atoms into a single quantum state is known as Bose- condensation. It was predicted by Satyendra Nath Bose and Albert Einstein in the 1920’s Atoms form a superfluid when cooled to temperatures near absolute zero.

10. Viscosity- The resistance of a liquid to flow is called Viscosity. Surface Tension- The result of attraction between molecules of a liquid which causes the surface of a liquid to act as a thin elastic film under tension. Causes water to form spherical drops. Vapor Pressure- The pressure that a solid or liquid exerts when it is in equilibrium with its vapor at a given temperature. Boiling Point- When vapor pressure=atmospheric pressure.
