GCSE Physics Flashcards
What is biofuels
Its the burning of plant based organsims like plant waste like dung, an exmaple of where it is palm oil (renewable)
What is nuclear power
It’s produced through clean and effecient way of boiling wager to make steam which turn a turbine to make electricity this can power homes (non renwable)
What is fossil fuels
It’s a non renewable energy source that usesburied carbon organisms like dehdrated wood to create coal,oil,natural gas and more these power electricity (non- renewable)
What is geothermal power
It is steam from the earth (hot water) found below the earths surface and the steam rotates a turbine that powers a generater to create electricity. (Renewable)
What is solar power
This energy from the sun that is turned into electricity this may be on top of houses schools on on farms or anywhere this can power electric cars to calculators to phones to more (renewable)
What is tidal energy
It’s energy from the sea thats quite deep and it uses tides and currents that move a turbine to generate power in a generator and create electricity (renewable)
What is wind energy
This uses energy from the wind by the use of wind turbines to generate electricity(renewable)
What is the three fossil fuels
Coal,oil,natural gas
What in the name for things that are used faster than they can be replaced
Non renewable energy resources
What is the name for where energy is stored
Energy stores
Skip
Skip
What is a non renewable energy source (give example)
Fossil fuels and nuclear fuels such as (Uranium and plutonium)
Where does fossil fuels come from
Underground,such as wood over millions of years. These can be burnt to provide energy.
What are the three fossil fuels
Coal,oil,(Natural)Gas
What do fossil fuels do examples
. They run out eventually
. They all do damage to the enviroment
. But they provide most of our energy
What are the 7 renewable energy sources
1) The sun (solar)
2) Wind
3) Water waves
4) Hydro-electricity
5) Bio-fuel
6) Tides
7) Geothermal
What does renewable energy mean
. These will never run out and can replenished while used
. Most of them do damage to the enviorment but not nasty like non-renewable energy
. The trouble is they don’t provide much energy and some of them are unreliable
because they depend on weather
What is a main way in which fuel is used (eg for work)
In transport
What resource is mostly used in the uk
Natural gas
What is a variable that is a controlled variable
Something you can change
The pie chart show porpotions of electricity generated in the Uk from different energy sources in 2010
16 Nuclear (percent)
7 Renewable
34 Coal
43 Gas
What makes up fossil fuels?
77 ( 34 coal + 43 gas )
Which of the following 3 are not a renewable energy source
Oil
Solar
Wind
Oil
In some types of power stations,fossil fuels are burned to heat ( ) to produce steam
Water
What is the answer
Carbon dioxide causes global warming
The wind is a unreliable or reliable source
Unreliable
Tides are a non renewable or renewable source
If wood is to be used as a renewable energy source, what must be done each time a tree is chopped down?
Plant/grow(at least) one new tree
Solar cells ( seeing from sun) are designed to transform _______________________________ energy into _______________________________ energy.
Light and electrical (in that order)
The aircraft propellers are driven by electric motors.
Give one environmental advantage of using electric motors to drive the aircraft propellers rather than motors that burn a fuel.
No air pollution
The world’s biggest offshore wind farm, built off the Kent coast, started generating electricity in September 2010.
One advantage of using the wind to generate electricity is that it is a renewable energy source. Give one other advantage of using the wind to generate electricity.
. Produces no emmisions
. Does not add to global warming
. Produces no air pollution
Name one renewable energy source used to create electricity
. Solar
. Wind
. Hydroelectric
. Waves
. Geothermal
. Biofuel/biomass
Use the graph to explain why the power output from the wind turbines was less than one sixth of the maximum.
Average wind speed below 6 m/s
Having more nuclear power stations will help to avoid power cuts in the future.
Nuclear fuels and the wind are two of the energy sources used to generate electricity in the UK. Explain the advantages of using energy from nuclear fuels to generate electricity rather than
(b)
using energy from the wind.
Include in your answer a brief description of the process used to generate electricity from nuclear fuels.
Small mass of fuel are able to generate a lot of electricty which allows for it to generate electrcity continuesly while not also being weather dependant due to it being able to run in any weather because it realise on energy from nuclear energy
Describe how ‘carbon capture’ would prevent the build-up of carbon dioxide in the atmosphere.
carbon dioxide is not released (into the atmosphere) but is (caught and) stored (in huge natural containers)
meaning the enviorment is not affected
