States of Matter Poster Assignment

By: Michael McInroy

Solids

Definition

Is the state of matter in which materials have a definite shape and a definite volume.

Details

  • Almost all solids have some type of orderly arrangement of particles at the atomic level.
  • Solids are often referred to as condensed phases because the particles are very close together.
  • Does not flow easily.

Examples

  • Gold
  • Wood
  • Copper

Liquids

Definition

Is the state of matter in which material has a definite volume but not a definite shape.

Details

  • A liquid always has the same shape as its container and can be poured from one container to another.
  • The forces between liquid particles are weaker than the forces between solid particles.
  • Liquid particles are further apart and can move about more easily.

Examples

  • Gasoline
  • Urine
  • Blood

Gases

Definition

Is the state of matter in which a material has neither a definite shape nor a definite volume.

Details

  • A gas takes the shape and volume of its container.
  • Pure gases are made up of just one atom.
  • Gas pressure is measured in pascals.

Examples

  • Propane
  • Hydrogen sulfide
  • Freon

Plasma

Definition

A highly ionized gas containing an approximately equal number of positive ions and electrons.

Details

  • Plasma is different from a gas, because it is made up of groups of positive and negatively charged particles.
  • Natural plasmas aren't found around you that often.
  • Man-made plasmas are everywhere.

Examples

  • Welding arcs
  • Fireball of a nuclear explosion
  • Interstellar gas clouds

Bose-Einstein Condensate

Definition

Is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero.

Details

  • Bose-Einstein condensate atoms are unexcited and super cold.
  • The BEC happens at super low temperatures.
  • You can create a BEC with a few special elements.

Examples

  • Laser
  • Liquid helium
  • Rubidium atoms
