States of Matter

States of Matter:

  • Particles are arranged in ordered, touching rows and cannot move, only vibrate.

  • Particles are touching but irregularly arranged, can move over each other and cannot be compressed.

  • Particles are not touching, are freely moving and so can be compressed.

Heat gives particles kinetic energy to overcome the forces holding them together.
Particles lose kinetic energy when cooled to overcome the forces that hold them together.
