Key Stage 2

Meaning

Liquid is a state of matter that can be poured but cannot be squashed into a smaller space.

About Liquids

Liquids are a state of matter that:

  • Can be poured and will flow.
  • Cannot hold their shape
  • Fit the shape of the container.

Liquids cannot be squashed into a smaller size. You can change their shape, but their size stays the same.

Examples of liquid materials:

  • Water
  • Oil

Key Stage 3

Meaning

Liquid is a State of Matter where the particles are in a random arrangement touching but can slide past each other.

About Liquids

  • A liquid can be poured and will flow because the particles can slide past each other.
  • Liquids cannot hold their shape because the particles can slide past each other.
  • Liquids fit the shape of the container because the particles can slide past each other.

Liquids cannot be compressed into a smaller volume because the particles are already touching so they can't get any closer together.

Key Stage 4

Meaning

Liquid is a State of Matter where the particles are in a random arrangement touching but can slide past each other.

About Liquids

When a substance is in its liquid state it is always more dense than in its gaseous state and usually less dense than its solid state. Water is an exception to this due to how the molecules arrange themselves when it is frozen as ice, see Ice-Water Anomaly.
A substance which is liquid at room temperature has a larger force of attraction between particles than a substance which is gas at room temperature but a weaker force of attraction than a substance which is solid at room temperature.

Particles can slide past each other. Liquids can be poured.
Liquids fit the shape of their container.
Convection happens in solids.
Particles and close together. Liquids cannot be compressed.
Sound passes through liquids faster than gases.
Thermal Conduction happens in liquids but not as well as in solids.
