Across
- 2. The movement of thermal energy from a warmer object to a cooler object is heat
- 4. A particle that consists of a nucleus of protons
- 6. Heat transfer by currents in a liquid or gas, warm liquids rise and the cold liquids sink
- 7. Energy cannot be created or destroyed, it can only be transformed or transferred
- 10. A place on a magnet where the force it applies is strongest
- 11. Any object that attracts the metal iron
- 14. A dense region of protons and neutrons at the center of an atom
- 15. A magnet that quickly loses its magnetic field after being removed from a magnetic field
- 17. Negatively charged particles
- 18. Heat transfer through direct contact of molecules within an object or between two objects
- 19. Transfer of heat through electromagnetic waves does not require matter to travel through
- 20. An object's ability to cause change
Down
- 1. A magnet that remains permanent after being removed from another magnetic field
- 3. Energy stored within an object due to its position or condition
- 5. The sum of the kinetic energy and the potential energy of the particles that make up a material
- 8. The state of a system in which all objects are the same temperature
- 9. Energy that is moving
- 12. The average kinetic energy of the particles that make up a material
- 13. A positively charged particle
- 16. A force of attraction or repulsion between the poles of two magnets
