These videos demonstrate the equipment and method for measuring the temperature change when burning different fuels
This video by SpaceyScience follows the specification for WJEC AS Level practical work. However, on some specifications this practical is recommended for 14–16 students. The method for measuring the enthalpy change for methanol and ethanol is shown. There are no calculations in the video so students could be given typical results and asked to calculate the enthalpy change for each of the fuels. The enthalpy change of combustion of other fuels can be determined in the same way. Students could be asked to write a method for, and predict the outcome of, burning propanol, butanol and pentanol.

We have collated these videos of key practical experiments to support remote teaching as part of our response to Covid-19. Teachers requested resources to help them deliver practical content without access to laboratories or equipment. We are developing further resources and welcome feedback to help us produce those you most need. Please email us or use the comment section below.
