Paper 1
A machine whose blades are turned by a moving fluid, such as steam, to provide rotary motion.
Revise: Fossil fuelsThe steam turns the blades of a turbine, which drives a connected generator. The generator converts this movement into electrical energy, supplying the electricity grid.
For electricity generation, explain the whole chain: burning fuel → heating water → steam → turbine → generator. The turbine turns; the generator produces electricity.
Explain the full generation sequence: fission releases heat, water becomes steam, steam turns a turbine, and the turbine drives a generator.
When explaining generation, link the stages: the wind or water turns a turbine, which drives a generator that produces electricity.
