Key knowledge:
• combustion of fuels as exothermic reactions with reference to the use of the joule as the SI unit of energy, energy transformations and their efficiencies and measurement of enthalpy change including symbol (ΔH) and common units (kJ mol-1, kJ g-1, MJ/tonne)
• the writing of balanced thermochemical equations, including states, for the complete and incomplete combustion of hydrocarbons, methanol and ethanol, using experimental data and data tables.
• the use of specific heat capacity of water to determine the approximate amount of heat energy released in the combustion of a fuel.
