Across
- 4. The energy stored in an object by raising it up. If it fell down to the ground all of this would be converted into kinetic/heat.
- 5. A form of hydroelectric power that uses the flow of the tides for electricity. Not necessarily waves.
- 8. Measure of how much matter an object has in a unit volume (cubic meter or cubic centimeter).
- 11. Thermal energy generated by the earth. Normally hot water heated by volcanic activity.
- 12. Heat Energy
- 15. The total amount of some quantity does not change
- 17. In heat conduction, energy is transferred from molecule to molecule by direct contact
- 18. “Heavy atoms are split into smaller lighter atoms, releasing kinetic energy.” Fission is started by colliding a slow moving neutron with a nucleus.
Down
- 1. Electricity provided by the energy of flowing water. This is often in dams created for this purpose.
- 2. A form of heat transfer by electromagnetic waves (infrared radiation). These are emitted or absorbed by the surface of objects.
- 3. Energy that is expressed through the movement of particles.
- 6. Movement Energy
- 7. An energy resource that will not run out for many human lifetimes. It is essentially infinite. The sun is a good example of this.
- 9. The percentage of energy that is used for a useful task and how much is wasted.
- 10. Material or process that prevents the transfer of heat by conduction, convection or radiation.
- 13. The unit for energy. [J]
- 14. Process by which heat is transferred by movement of a heated fluid such as air or water
- 16. Oil, Coal, Natural gas and other fuels that are made from the remains of buried dead organisms. Created over millions of years by intense pressure.
