Year 8 Chemistry States of Matter

Flashcards for Year 8 Chemistry Notes on States of Matter

Solid

A state of matter where particles are tightly packed together and vibrate in place. Difficult to compress.

Liquid

A state of matter where particles are close but can slide past each other, allowing for pourability. Takes the form of its container and is difficult to compress.

Gas

A state of matter where particles are far apart and move freely. Takes the form of its container and can be compressed easily.

Melting

The change of state from solid to liquid.

Vaporisation

The change of state from liquid to gas.

Condensation

The process of gas converting back to the liquid state of matter.

Freezing

The process of liquid converting to solid.

Deposition

The process of gas converting directly to solid.

Sublimation

The process where a solid converts directly into a gas, skipping the liquid step.

Particle Theory

All matter is made up of tiny particles.
