The States of Matter Review

Solids

• Fixed Volume and Shape
• Very little space between particles
• Particles can only vibrate in place
• Not easily compressible
• Particles usually in a pattern

Liquids

• Fixed volume but indefinite shape
• Shape changes to whatever object it is in
• Particles are close together, but not as close as solids
• Particles can "slide and glide"
• Solid water is less dense than liquid water

Gases

• No fixed shape or volume
• Particles are not close together
• Particles can move in any direction
• Easily compressible
• No regular arrangement in particles

Plasma

• Gases that are electrically charged
• Most common state of matter in Universe, but not on Earth
• Found on Earth in: Plasma TVs, fluorescent lights, and lightning
• Makes up stars

Bose-Einstein Condensate

• Most recently discovered state of matter
• Form when supercooled to close to 0 kelvin
• 0 kelvin is the temperature when molecules stop moving
• 0 kelvin is also known as "absolute zero"
• 0 kelvin does not exist anywhere that we know of

Patterns

• Space between particles increases as you go from:
• Solid->Liquid->Gas
• Amount of movement of particles increases as you go from:
• Solid->Liquid->Gas
• Solids are more dense than liquids unless it is water.
