States of matter: particle model simulation

Move the temperature slider to take water through melting and boiling, and watch how the arrangement and movement of the particles change.

Questions students ask

Why does the temperature stay the same while ice melts?

The energy supplied (latent heat) goes into breaking the forces between particles rather than making them move faster.

Why can gases be compressed but solids cannot?

Gas particles are far apart with lots of space between them; in a solid the particles are already touching.
