States of Matter
BY Johnathan Stephens
Solids
- Solids-Molecules packed closely together
- Low Kinetic Energy
- Definite Volume
- Definite Shape
- Example 1: pencil
- Example 2: ice cube
Liquids
- Liquids- Molecules are close together but move freely
- Definite Volume
- Takes Shape of Container
- Medium Kinetic Energy
- Example 1:Milk
- Example 2: Juice
Gas
- Gas-Molecules are far apart and move freely
- No Fixed Volume
- No Definite Shape
- High Kinetic Energy
- Ex 1:Hydrogen
- Ex 2:Oxygen
Plasma
- Plasma-Particles that have extremely large amounts of energy
- Gas made up of electrons
- Most common phase of matter in the universe
- Responds to electromagnetic fields
- Ex 1: Dark Matter
- Ex 2: Lightning
Bose Einstein Condensate (BEC)
- (BEC)-A Dilute Gas of Bosons That Is Cooled Near Absolute 0
- Einstien predicted it in 1920's
- Scientist finally created it in 1995
- Groups of atoms behave as if they are a single particle
- Ex 1: Cold Liquid Helium
- Ex 2: Nucleons of a Neutron Star
