Across
- 4. The flow of electrons through a conducting wire
- 8. energy that travels as waves and can move through empty space
- 9. the ability to do work or cause change
- 11. the energy associated with the motion or position of an object, either as potential or kinetic energies
- 12. The only heat transfer that does not require particles of matter and that can transfer through empty space.
- 17. the energy an object has due to its motion
- 18. Circuit in which there are multiple paths for the electrons to flow. A break in one 'branch' of the circuit still allows other branches to remain lit.
- 19. the energy of electrically charged particles moving from one place to another
Down
- 1. A temporary magnet caused by a current carrying wire that is wrapped in coils around an iron or metallic core.
- 2. The potential difference between electrodes in a cell that 'pushes' the electrons to flow through the circuit.
- 3. The change form a liquid to a gas at the boiling point (water: 100 degrees C).
- 4. A change from one form of energy to
- 5. Related to the number of electrons passing a certain point per unit of time
- 6. Heat transfer in fluids (liquids and gases) due to differences in density (which causes movement within the molecules of the fluid)
- 7. the total energy of the moving particles in an object;also known as heat energy
- 10. Energy that is stored and held in readiness; energy of position
- 13. Heat transferred by direct contact (for example from an iron to a shirt or a stove to a pan).
- 14. The build-up of 'static' charges (+ or -) on an object due to friction. Like charges repel and opposite charges attract.
- 15. potential energy stored in chemical bonds of molecules
- 16. Slows the flow of electrons and is a property of the metal being used in a circuit.
