Across
  1. 3. conduction occurs within a material as faster moving particles blank thermal energy by colliding with slower moving particles
  2. 4. have different features that help them control heat flow
  3. 8. gases are pushed out of cylinders
  4. 12. are in constant random motion
  5. 13. sum of the kinetic energy and potential energy of the particles in an object
  6. 15. transfer of thermal energy by collisions between particles in matter at higher temperatures
  7. 16. of air in please make it a good insulator
  8. 17. device that converts thermal energy into work
  9. 19. material in which electrons are not able to move easily
  10. 20. measure of the average kinetic energy of all the particles in an object
  11. 21. molecules hold strong bonds when the specific heat of water is
  12. 24. not all of the blank radiation reaches earth
  13. 26. transfer of thermal energy in a fluid by the movement of water and cooler fluid from one place to another
  14. 27. an amount of thermal energy needed to raise the temperature of 1kg of material 1C
  15. 28. evaporates from your skin it carries he away, cooling your body
  16. 29. transfer of thermal energy through electromagnetic waves
  17. 30. states that the increase in thermal energy of a system equals the work done to the system plus the heat added to the system
Down
  1. 1. state that is impossible for heat to flow from a cool object to a warmer object and less work is done
  2. 2. movement of a piston in an automobile engine consists of four separate strokes
  3. 5. electrons can move freely
  4. 6. air pump can be a system
  5. 7. air systems, air heated by the furnace gets blown through ducts that usually lead to every room
  6. 9. uses a vacuum and reflective surface is to reduce flow of heat into and out of the bottle
  7. 10. device used in an active solar heating system that absorbs radiant energy from the sun
  8. 11. thermal energy that flows from warmer material to a cooler material
  9. 14. heat engine that burns fluid inside the engine in chambers or cylinder
  10. 18. study of the relationship between thermal energy, heat and work
  11. 22. in temperature increases thermal energy
  12. 23. fuel in the engine cylinder, produces thermal energy that is converted into work
  13. 25. used to measure the specific heat of materials
