-
Gases behaviors
You can compress with very little pressure. Do not want to be contained and will escape whenever possible
-
What happens when a liquid has been sitting in one place for a while
It becomes a gas.
-
Gas and energy
All gases have different energies.
-
What is plasma?
Similar to gas, but plasma's electrons and ions are more bouncy.
-
Plasma example
Northern Lights
-
Plasma is
Super hot! In everyday and night objects.
-
Superfluids are also known as
B E condensate (Bose-Einstein condensate)
-
How were superfluids identified?
In 1995, two scientists--Cornell and Weiman--made this new state of matter.
-
Why are superfluids also known as "Bose-Einstein Condensate"?
Albert Einstein and Satyendra Bose predicted a fifth state of matter.
-
What are superfluids like?
Complete opposite on plasma spectrum and are extremely cold. "Like 0 degrees Kelvin cold" (-460 degrees Farenheit). Kelvin 0 is "Absolute zero"
-
What did Carl Weiman and Eric Cornell use for their superfluids?
Rubidium
-
What did the process for making a superfluid look like?
The atoms clumped together into a super blob.
-
Solutions are. . .
homogeneous.
-
Solutions can be
solids in liquids, liquids in liquids, gases in liquids, gases in solids, and solids in solids.
-
A simple solution has
. . .a solute and a solvent.
-
Coenerd's (? spelling?) rule
There is more solvent than solute.
-
What happens when solvent meets solute?
- The solute is placed in the solvent and the concentrated solute breaks down.
- The molecules of the solvent begin to move out of the way to make room for the solute's molecules.
- The solvent and the solute interact with each other until the concentration of the two is equal throughout.
- The concentrate of solute will the the same no matter what.
-
Mixtures are. . .
everywhere you look. Most things in nature are mixtures.
-
Mixtures. . .
- Individual molecules enjoy being together.
- Bananas contain.
- There are an infinite number of mixtures.
- Substance can be separated physically in mixtures.
-
You can identify matter by . . .
- Texture
- odor
- properties: color, luster, malleability,
- melting or freezing or boiling point
- conductivity
- density
- solvency
-
Mass
How much matter is in an object.
-
Weight
How much gravitational force is acting on the object.
-
Volume
How much space an object takes up.
-
Density =
mass / volume (mass over volume)
