Across
  1. 5. a method of energy conservation by which waste heat or energy from one industry is used by another industry
  2. 7. materials that slow the transfer or conduction of thermal energy from one object to another (two words)
  3. 8. materials that lack a definite shape and can flow from one place to another
  4. 9. liquids that evaporate easily at low temperatures
  5. 12. a type of heating that uses materials in a structure to absorb, store, and release solar energy (three words)
  6. 15. energy generated in the interior of Earth
  7. 16. energy that is transmitted via electromagnetic waves
  8. 17. a warming of the environment that results from human activities (two words)
  9. 18. a flow resulting from the rising of warm materials and the sinking of cooler, denser materials (two words)
  10. 20. a process by which a warm fluid moves from place to place carrying thermal energy
  11. 21. energy from the sun
Down
  1. 1. solid, liquid, or gas hydrocarbons formed from the soft parts of plants and animals over millions of years and trapped inside the Earth during the planet's formation (two words)
  2. 2. an object or material that can transfer energy to other objects (two words)
  3. 3. a type of heating that uses mechanical devices like fans to distribute stored thermal energy (three words)
  4. 4. resources that take millions of years to form (two words
  5. 6. the transfer of energy in the form of electromagnetic waves
  6. 10. process in which the faster-moving particles on the surface of a liquid evaporate and escape into the air while the slower moving particles, which are left behind, have lower kinetic energy and decrease the temperature of the remaining liquid and the surface on which it is resting (two words)
  7. 11. material has no particular shape or size and can be compressed
  8. 13. mechanical systems and devices, usually containing water, or air, used in active solar heating systems (two words)
  9. 14. the direct transfer of thermal energy from one particle or object to another through contact or collision (two words)
  10. 19. energy resources that can be recycled or replaced by natural processes in less than 100 years
