Across
  1. 4. these materials conduct thermal energy poorly
  2. 5. a temperature of zero degrees Kelvin, it would cause a lack of motion of all particles
  3. 7. the law that states absolute zero can not be reached
  4. 9. the transfer of thermal energy as particles flow from one place to another in a cycle
  5. 10. the law that states thermal energy can flow from colder to hotter objects if work is done
  6. 12. the transfer of thermal energy from one material to another
  7. 13. the transfer of thermal energy through contact of materials

  9. 15. the transfer of energy by waves moving through space
Down
  1. 1. an increase in an objects volume due to it's temperature increase
  2. 2. when fluid circulates in a loop as it alternately heats up and cools down
  3. 3. the law that states energy is conserved
  4. 6. the measure of how hot or cold an object is

  6. 9. materials that transfer thermal energy well
  7. 11. the study of conversions between thermal and other forms of energy
