Core
- Describe the meaning of exothermic and endothermic reactions
- Describe the production of heat energy by burning fuels
- Describe hydrogen as a fuel
- Describe radioactive isotopes, such as 235U, as a source of energy
Supplement
- Describe bond breaking as endothermic and bond forming as exothermic
- Describe the production of electrical energy from simple cells, i.e. two electrodes in an electrolyte. (This should be linked with the reactivity series in section 10.2 and redox in section 7.3.)
- Describe the use of hydrogen as a potential fuel reacting with oxygen to generate electricity in a fuel cell (details of the construction and operation of a fuel cell are not required)
