Air

Air

Objective: To learn about air. Learning outcomes - students will be able to: 1. Define air and its composition 2. Discuss the percentage of different gases present in air 3. Explain that air occupies space
Application of Radioisotopes

Application of Radioisotopes

Radioisotopes are unstable atoms that emit radiation, and decay to form stable atoms. Some of their uses are as nuclear fuel and as tracers in medicinal fields.
Applications of Colloids in Everyday Life

Applications of Colloids in Everyday Life

This video defines colloids and explains their importance in pharmaceutical preparations.
Applying the Concepts

Applying the Concepts

The programme covers Le Chatelier's principle, the equilibrium law, calculating K. It examines how K changes when the temperature of exothermic and endothermic reactions changes, with a focus on sulphuric acid manufacture.
