Try this tutorial with accompanying videos to help teach students on post-16 courses about the concept of entropy and the second law of thermodynamics.

Entropy gives scientists a mathematical way of measuring randomness, relating to the number of arrangements of particles that lead to a particular state.

This tutorial is designed to develop and consolidate students’ understanding of entropy as a fundamental concept in thermodynamics. Students build on their knowledge about the chance behaviour of particles and energy to learn about:

The second law of thermodynamics
The role of energy in determining the entropy or randomness of a chemical system
Entropy change and how to calculate it

The tutorial also features video demonstrations and animations to illustrate key ideas.
