Solid, Liquid and Gas

There are three states of matter. Glue in your diagram that shows how to move from each state to state.

The Particles

In each state of matter the particles are arranged differently because they have different amounts of energy. Energy means temperature.

Source

Solid

  • The atoms are neatly arranged,
  • are tightly packed,
  • can vibrate but not move freely,
  • and have the lowest energy (coldest).
Source

Liquid

  • The atoms are close together,
  • do not have a particlar arrangement,
  • can move past and around each other,
  • move to fit the shape of the vessel,
  • and have a medium energy.

Gas

  • The atoms are free-moving,
  • do not have a particular arrangement,
  • move and collide with each other,
  • fill the volume of a vessel,
  • and have a high energy (hot).

In Summary!

  • A high energy \(\rightarrow\) high speed \(\rightarrow\) gas
  • A low energy \(\rightarrow\) low speed \(\rightarrow\) liquid
  • Very low energy \(\rightarrow\) no speed, vibration only \(\rightarrow\) solid

It’s All About Energy

  • Atoms in liquids have more energy than those in solids.
    • Therefore, to turn a solid into a liquid you must add energy (heat)!
  • Atoms in gasses have more energy than those in liquids.
    • Therefore, to turn a liquid into a gas you must add energy (heat)!
  • Atoms in solids have less energy than those in liquids.
    • Therefore, to turn a liquid into a solid you must remove energy (heat)!
