Across
- 2. Energy of motion or stored, driver of renewable energy. (swings, bounces, spins)
- 4. The movement of electrons from one atom to another.
- 7. change Matter changes from one state to another (solid, liquid, gas).
- 8. Flow of thermal energy from hot to cold.
- 9. Kinetic energy that is visible to humans (ROYGBIV).
- 13. Neutrons combine and split releasing a chain reaction (nuclear power).
- 14. SI unit used to measure temperature; 0K or -273 degrees C is absolute O.
- 15. Mechanical energy moves as vibrations.
- 17. Energy held due to position, stored energy.
- 20. Energy easily made again: solar, wind, hydro (water), geothermal, biomass
- 22. Energy in the core of an atom.
- 23. Stored energy in the bonds of atoms.
Down
- 1. Energy from EM radiation then radiates to the surrounding environment.
- 3. Energy not easily made again: fossil fuels (coal, oil, natural gas, petroleum, propane) and nuclear (fusion, fission)
- 5. of conservation of energy Energy cannot be created or destroyed, it can only change forms.
- 6. Heat energy is conducted to the point of heat first then in circular motion throughout (water, air).
- 10. Energy that is responsible for its temperature.
- 11. Heat energy is transmitted through two objects touching.
- 12. Energy stored due to its height above the Earth.
- 13. Two nuclei combine to form a new nucleus (the sun).
- 16. Energy of motion.
- 18. zero -273 degrees C is OK, the point that all molecules stop moving.
- 19. Energy stored by applying force (compression, stretching, or twisting).
- 21. Measure of hot or cold expressed in Fahrenheit, Celsius, or Kelvin.
