Thermal Energy

4. Limits or restrictions on a design (such as cost, size, materials, or time)
7. The first model of something used to test a concept or process
8. The total kinetic energy of particles in a substance; related to heat and temperature
9. The movement of thermal energy from one object to another
13. Transfer of heat by movement of fluids (liquids or gases)
14. A material that easily allows the flow of heat
15. Transfer of heat through electromagnetic waves

1. Making the best or most effective use of a situation or resource
2. Transfer of thermal energy through direct contact
3. A measure of the average kinetic energy of particles in a material
5. The energy an object has because of its motion
6. The practice of using less energy or preventing energy loss
10. When two objects reach the same temperature and no heat flows between them
11. A group of interacting parts considered together for study
12. A material that slows down heat transfer
