- 3. A rapid back-and-forth movement of particles in a substance, which can create sound or heat.
- 4. The process of heat transfer through direct contact.
- 6. The transfer of heat from one location to the next by movement of fluids.
- 8. An instrument used to measure temperature, often containing a liquid that expands or contracts based on heat.
- 9. A substance that can flow; includes liquids and gasses, which take the shape of their container
- 11. The transfer of energy through electromagnetic waves, which can occur in a vacuum (empty space) without needing a medium.
- 12. A measure of how hot or cold something is, which reflects the average kinetic energy of its particles.
Down
- 1. Referring to objects or phenomena that can be seen and measured without the use of a microscope, visible to the naked eye.
- 2. Waves of energy that travel through space at the speed of light, including visible light, radio waves, and infrared radiation.
- 5. The mean energy of motion of the particles in a substance; it increases as temperature increases.
- 7. The energy that is transferred from one object to another due to a temperature difference.
- 10. radiation A type of electromagnetic radiation with wavelengths longer than visible light; it is often felt as heat.
