Solid - GCSE Chemistry Definition

Reviewed by: Richard Boole

Published

A solid is a state of matter where particles are packed closely together in a fixed arrangement. This means that solids have a definite shape and volume, unlike liquids and gases, which can change shape. The particles in a solid vibrate, but they do not move from their positions, which makes solids rigid and firm. Common examples of solids include ice, wood, and metal. In GCSE Chemistry, understanding solids is important because their properties, such as melting point and density, can help us to identify substances and predict how they will behave in different situations.

Expertise: Chemistry Content Creator

Richard has taught Chemistry for over 15 years as well as working as a science tutor, examiner, content creator and author. He wasn’t the greatest at exams and only discovered how to revise in his final year at university. That knowledge made him want to help students learn how to revise, challenge them to think about what they actually know and hopefully succeed; so here he is, happily, at SME.
