A liquid can flow, has a fixed volume and takes the shape of the bottom of its container.

The three common states of matter are solid state, liquid state and gas state.

A gas can flow, has no fixed volume and takes the shape of the whole of its container.

Evaporation is the change of state from a liquid to a gas.

Condensation is the change of state from a gas to a liquid.

Science

In this Introduction to states of matter and changing states unit, pupils learn that some materials change state when they are heated or cooled. In the Properties, changes and separating materials unit, they will build on this knowledge to learn that dissolving, mixing and changes of state are reversible changes

In the Everyday materials unit, pupils learnt to compare and group together a variety of everyday materials on the basis of their simple physical properties. In this Introduction to states of matter and changing states unit, pupils will build on this knowledge to compare and group materials together according to whether they are solids, liquids or gases
