Bose-Einstein
•Gas has no definite volume or shape.
•Gas will expand indefinitely
•Low density causes even distribution of gasses in containers
Gas
• Definite volume but can change by flowing
• Molecules touch but are able to move around
• Liquids take the shape of their container
Definite shape and volume Tightly packed atoms They are ridged
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.
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
• 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.
• 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.
• 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.
