Key Stage 2

Meaning

State of matter means whether a material is solid, liquid or gas.

About States of Matter

Materials can be solid, liquid or gas.
The state of matter can be changed by heating or cooling the material.
Heating can turn a solid into a liquid and turn a liquid to a gas.
Cooling can turn a gas into a liquid and liquid into solid.

Solid

Solids are a state of matter that:

  • Hold their shape if you leave them alone.
  • Do not flow.
  • Keep the same size even if you squash them they might get longer, but they also get thinner keeping the same size overall.

Examples of solid materials:

  • Brick
  • Wood
  • Plastic
  • Glass
  • Ice

Liquid

Liquids are a state of matter that:

  • Cannot hold their shape
  • Fit the shape of the container.
  • Can be poured and will flow.
  • Keep the same size. If you pour water into different shaped containers the water will not spread out or fit in a smaller space.

Examples of liquid materials:

  • Water
  • Oil

Gas

Gases are a state of matter that:

  • Cannot hold their shape.
  • Fit the shape of their container.
  • Can be poured and will flow.
  • Can change size to fit the size of their container. They spread out and can be squashed into a smaller space.

Examples of gas materials:

  • Air (A mixture of gases, mostly nitrogen and oxygen)
  • Steam
