Experiment
Ammonium dichromate volcano
Create your own ‘mini volcanic eruption’ – complete with sparks, ‘ash’, steam and nitrogen as ammonium dichromate is ignited and decomposes exothermically.

Experiment
Combustion of hydrogen in air
In this experiment hydrogen is burnt with some air. The aim of the experiment is to find out how much air is needed to burn hydrogen most efficiently.

Experiment
Exothermic metal displacement reactions
Students add powdered metals to a copper(II) sulfate solution and measure the temperature rises.
-
Experiment
Supercooling - the energetics of freezing
Students melt sodium thiosulfate crystals, and these are then cooled to a state well below the melting point. The supercooled liquid will freeze rapidly on the addition of a crystal of sodium thiosulfate, or on stirring which seeds the crystallisation process. Temperature changes are observed throughout.

Experiment
Fat-pan fire!
The context of a fat-pan (chip-pan) catching fire is used to demonstrate the conditions required to start combustion, and how to put such a fire out safely.
-
Experiment
Exothermic metal-acid reactions
Students add powdered or finely-divided metals to hydrochloric acid and measure the temperature changes.

Experiment
Comparing heat energy from burning alcohols
Investigate the amounts of heat energy produced by the combustion of different alcohols in this class experiment. Includes kit list and safety instructions.

Resource
The second law of thermodynamics
This activity aims to introduce the topic in a way that uses the students’ synthesis skills to piece together several pieces of information.

Experiment
The alcohol gun
Illustrate the large energy changes that take place during the combustion of alcohols with this spectacular demonstration.

Energy
Knowledge of energetics can help understand the process of a reaction and the conditions under which it operates. It also develops knowledge of the link between individual bond energies and the net energy gain or loss as well as the realisation that energy is not just heat. This programme is ...
