7I Energy

3. Any fuel that comes from living things; plants, animals, or their wastes.
4. energy The kind of energy stored in chemicals. Food, fuels and cells (batteries) all contain chemical energy.
7. An energy resource that will never run out.
8. Process that plants use to make their own food.
10. Energy stored inside the nucleus of the atom.
13. Fossil fuel formed from the remains of dead plants and animals that lived in the sea.
15. current A flow of liquid or gas caused by part of it being heated or cooled more than the rest.
17. The unit for measuring energy.
18. The kind of energy made by anything that is making a noise.
20. Any energy resource that will run out.
21. The hotter something is, the more heat energy it has.
25. Making electricity by letting falling water turn turbines and generators.
26. A fossil fuel made from the remains of plants.
27. A dead organism that has been trapped in mud and whose body has not completely rotted away.
28. Fossil fuel natural gas formed from the remains of dead plants and animals that lived in the sea.

1. These convert light energy into electrical energy.
2. Large coil of wire with a magnet inside which makes electricity
5. fuels Coal, oil and natural gas – all fuels that were formed from the remains of dead plants and animals.
6. There are 1000 joules in 1 kilojoule.
9. This is pushed round by water or steam and turns the generator.
11. A nuclear fuel.
12. The idea that energy can never be created or destroyed, only changed from one form into another.
14. Making electricity using heat from hot rocks underground.
16. Flat plates that use the Sun's energy to heat water.
19. Make electricity by turning a magnet inside coils of wire.
22. The kind of energy in moving things.
23. Dangerous particles and energy given off by radioactive materials.
