Physics P1 4.1 Fuel for electricity.

HideShow resource information
What are electricity generators in power stations driven by?
Turbines.
1 of 15
What is burned in fossil-fuel power stations?
Coal, oil and natural gas.
2 of 15
What is used as the fuel in a nuclear power station?
Uranium or plutonium.
3 of 15
What are biofuels?
Biofuels is any fuel obtained from living or recently living organisms and are renewable sources of energy which can generate electricity. Some can be used in small-scale gas-fired power stations.
4 of 15
Why do most power stations burn fuels?
To produce energy to heat water to produce steam..
5 of 15
In a nuclear power station how is uranium used to produce energy ?
Uranium is not burned, the energy comes from the process of nuclear fission.
6 of 15
Why do most power stations heat water to produce steam?
The steam drives a turbine which is coupled to an electrical generator that produces the electricity.
7 of 15
Where are fossil fuels obtained from?
Long-dead biological material.
8 of 15
What happens in some gas-fired power stations and how is this advantageous?
Hot gases may drive the turbine directly and a gas-fired turbine may be switched on very quickly.
9 of 15
What process can a uranium atom undergo to release energy?
Nuclear fission. There are lots of uranium nuclei so lots of fission reactions take place releasing lots of energy, this energy is used to heat water and turn it into steam.
10 of 15
What are the advantages of nuclear power stations?
Much more energy is released per kilogram of uranium undergoing fission reactions than from each kilogram of fossil fuel that we burn, also nuclear power stations do not release any greenhouse gases, unlike fossil-fuel power stations.
11 of 15
What are the disadvantages of nuclear power stations?
They produce radioactive waste that must be safely stored for a long period of time.
12 of 15
Name some fossil fuels?
Coal, oil and gas.

What is the process by which energy is produced in a nuclear station?
Nuclear fission.
