Energy Transfer

1. A measure of how hot or cold something is,which reflects the average kinetic energy off its particles
4. The energy that is transferred from one object to another due to a temperature difference
7. Referring to objects or phenomena that can be seen and measured without the use of a microscope; visible to the naked eye.
8. The process of heat transfer through direct contact between materials, where energy moves from warmer areas to cooler areas
10. Waves of energy that travel through space that the speed of light, including visible light, radio waves and infrared radiation
11. A rapid back-and-forth movement of particles in a substance which can create sound or heat
12. A type of Electromagnetic ration with wave lengths longer than visible light;it is often felt as heat

2. The mean energy of motion of particles in a substance; it increases as temperature increases
3. An instrument used to measure temperature, often containing a liquid that expands or contracts based on heat
5. The transfer of heat from one location to another by the movement of fluids.
6. A substance that can flow;includes liquids and gasses,which take the shape off their container
9. The transfer of energy through electromagnetic waves, which can occur in a vacuum without needing a medium
