Energy
Across
- 2. reflects and forces sunlight onto a fluid pipe, thermal energy is used to create steam, which turns the turbine wind energy
- 4. energy that travels as waves through matter or through empty space
- 5. solar cell can change light energy into electricity
- 7. heat energy from inside the earth that can be used to heat buildings and produce electricity
- 8. energy of moving charges (lamps, toasters)
- 10. a change form one form to another
- 11. can be replaced as it is or cannot be used up
- 14. the ability to make things move or change
- 15. energy of moving air( wind turbines)
- 16. energy from the sun
- 18. energy stored in the bonds that hold atoms together
- 19. energy stored in the nucleus of an atom
- 20. careful use of resources
Down
- 1. an energy resource that formed over millions of years from decayed remains of plants and animals
- 3. energy of moving objects (car moving)
- 6. the energy of moving particles (hot cocoa has many)
- 9. used up much faster than it can be replaced
- 12. any material from living things that can be used as an energy source
- 13. store electrical energy produced by solar cells
- 17. energy of moving water
