Energy and chemistry

Energy and Chemistry is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and experimental ideas from members of the association that had appeared in the ASE journal, School Science Review.

The sections of this resource and the topics are as follows.

Energy transfer
* Heat, the movement of molecules
* Energy conversion using a drawing pin
* Light energy controlling sound energy
* A simple heat engine
* A pure heat engine
* A simple demonstration steam turbine
* Hero's engine
* Lemery's volcano
* Gas, vapour and dust explosions
* Polythene flask used in full view of the class for the oxygen-hydrogen explosion
* The explosion of gaseous mixtures
* On combining heat content diagrams
* Model to illustrate energy changes in chemical reactions

Measuring energy changes
* The enthalpy change of vaporization
* Cheap calorimeter cases from waste polystyrene
* A simple experimental test of Hess's law
* The calorific value of coal gas
* An experiment with 'meta' fuel
* Experiment to measure the heat of combustion of sulphur
* Heat of reaction
* Calorimetry of the hand
* Measuring the energy of the carbon-bromine bond.

Activation energy
* Experiment to show the principle of the Davy lamp
* The catalytic oxidation of alcohols using the principle of the safety lamp
* The experimental verification of the Arrhenius temperature-reaction rate relationship and the determination of an energy of activation
* The activation energy of the thiosulphate-acid reaction
* Activation energy determinations

Experiments for the sixth form student; aspects of energy changes
* A financial analogue of the laws of thermodynamics
* A heat engine run by rubber
* The thermodynamics of rubber
* Free energy changes? Introducing standard free energy early in the energetics course
* Practical measurement of entropy changes
