Across
- 4. unit used to express energy
- 5. a measure of how hot or cold something is; a measure of the average kinetic energy of the particles in an object
- 6. a material that allows heat to flow easily through it
- 9. a force that opposes motion between two surfaces that are in contact
- 10. heat transfer through direct contact of molecules
- 11. energy of a compound that changes as its atoms are rearranged (reacts)
- 14. the capacity to do work
- 15. The energy of moving electrons
- 17. states that energy cannot be created or destroyed but can be changed from one form to another
- 19. a change from one form of energy to another
- 20. heat transfer through empty space, in the form of electromagnetic waves
Down
- 1. form of mechanical energy, stored energkineticenergy form of mechanical energy that moves
- 2. the amount of work an object can do because of the object’s kinetic and potential energies
- 3. energy something has due to its height or weight
- 6. Kinetic energy of a substance’s particles, More movement, more heat
- 7. Produced by the vibrations of electrically charged particles thru electromagnetic waves. can travel through matter or a vacuum
- 8. Caused by an object’s vibrations. A vibrating object transmits energy through waves in air around it
- 12. energy that comes from changes in the nucleus of an atom (either splits atoms(fission) or fuses them (fusion)
- 13. movement of heat by transfer of energy from one object to another
- 16. the energy transferred between objects that are at different temperatures
- 18. heat transfer by movement of a fluid like air or liquid
