Changes of State All changes of state are physical changes, so the identity of the substance doesn’t change.

Any change from a solid to a liquid is called melting. In most pure substances this occurs at a specific temperature, called the melting point. Thermal.

Solid Liquid Gas

Solid solidification Liquid Gas

Changes of State Solidification (freezing) – when a liquid turns into a solid (because the particles slow down and lose/release energy)

Solid solidification Liquid Gas

Solid solidificationfusion Liquid Gas

Fusion (melting) – when a solid turns into a liquid (because the particles gain energy and move faster)

Solid solidificationfusion Liquid Gas

Solid solidificationfusion Liquid condensation Gas

Condensation – when a gas turns into a liquid (because the particles slow down and lose/release energy)

Solid solidificationfusion Liquid condensation Gas

Sublimation – when a gas turns into a solid or a solid turns into a gas without turning into a liquid.

Discuss changes the students have seen in their everyday lives – e.g. “sweat” on cold drinks, snow melting, opening the freezer door and seeing “steam”, “steam” from the river in the fall, etc.
