Quick explanation
Define density as mass per unit volume
- This point belongs to Changes of state and the particle model, especially Density of materials.
- You need to be able to define density as mass per unit volume.
- The key ideas to know are density, volume, and mass.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Quick student answer
What is density?
Direct answer
In Physics, this page helps you answer questions about density within Changes of state and the particle model. Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are Density and Mass.
Key terms
- Density: The mass of a substance per unit volume, typically expressed in kilograms per cubic meter (kg/m³) or grams per cubic centimeter (g/cm³).
- Mass: The amount of matter in an object, measured in kilograms (kg), distinct from weight which is the force exerted by gravity on that mass.
Common trap
Confusing Density with Weight: Remind students that density is defined as mass per unit volume, and that two objects can have the same weight but different densities if their volumes differ.
