Unit 1 Power station

What is the first step in generating electricity at the power station?

• Steam turns a turbine

• Coal is transported from a storage area to a boiler

• Hot water turns into steam

• Electricity travels along power lines

Coal is burned in the _______ to produce heat

What turns the turbine to generate electricity?

• Hot water

• Coal

• Steam

• Electricity

The steam produced from the heated water is used to turn a _______.

Explain how coal is used to produce electricity in the power station, based on the diagram. Tell me what happens at 1, 2 and 3.

What happens to the electricity after it is generated by the moving turbine?

• It is cooled down

• It travels along power lines over long distances

• It turns back into steam

• It is stored in the boiler

If the boiler did not work, what part of the electricity generation process would be affected first?

• The heating of water to produce steam

• The movement of the turbine

• The travel of electricity along power lines

• The reduction of energy by transformers

Which part of the process involves a change from heat energy to mechanical energy?

• When coal is burned

• When hot water turns into steam

• When the turbine is turned by the steam

• When electricity travels along power lines

Compare the roles of the boiler and the turbine in generating electricity. How do they work together?
1. Tell me what the boiler does

2. 2. Tell me what the boiler does to the turbine

3. 3. Tell me what type energy to changes from and into i.e. movement energy into heat energy

Which of the following steps is most critical in ensuring electricity reaches homes safely?

• Burning the coal

• Turning the turbine

• Heating the water

• Transformer
