Quick explanation
Explain entropy as a measure of dispersal of energy or disorder
- This point belongs to Thermodynamics (A-level only), especially Entropy and Gibbs free energy (A-level only).
- You need to be able to explain entropy as a measure of dispersal of energy or disorder.
- The key ideas to know are entropy.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Entropy and Gibbs free energy (A-level only) to exam-style questions, flashcards, and revision notes for Thermodynamics (A-level only).
Quick student answer
Which of the following best describes entropy?
Direct answer
A measure of the dispersal of energy or disorder in a system
Key terms
- Entropy: A measure of the dispersal of energy or disorder in a system.
- Gibbs Free Energy: A thermodynamic potential that measures the maximum reversible work obtainable from a thermodynamic system at constant temperature and pressure.
Common trap
Confusing entropy with energy: Remember that entropy specifically measures disorder or energy dispersal, not total energy.
