Task 4 Tempereture and Heat

Give your science idea  and the reason following statement below :

  1. Ice cannot change temperature
  2. When the temperature of a boiling substance remains constant, something is “wrong.”
  3. The bubbles in boiling water contain “air,” Oxygen,” or “nothing,” rather than water vapor.
  4. All liquids boil at 100°C (212°F) and freeze at 0° C  (32°F).
  5. Heat is a substance.
  6. Heat is not energy.



  7. Temperature is a property of a particular material or object (metal is naturally colder than plastic).
  8. The temperature of an object depends on its size.
  9. Heat and cold are different, rather than being opposite ends of continuum.
  10. Boiling is the maximum temperature a substance can reach.
  11. Objects of different temperatures which are in constant contact with each other, or in contact with air at a different temperature, do not necessarily move toward the same temperature.
  12. Heat only travels upward.
  13. Heat rises.
  14. The kinetic theory does really explain heat transfer. (It is recited, but not believed.)
  15. Objects which readily become ware (conductors of heat) do not readily become cold.
  16. All solids expand at the same rate.
  17.  
  18. Heat is a substance.
  19. Heat is not energy.
  20. Temperature is a property of a particular material or object. (Metal is naturally cooler than plastic).
  21. The temperature of an object depends on its size.
  22. Heat and cold are different, rather than being opposite ends of a continuum.
  23. When temperature at boiling remains constant, something is "wrong".
  24. Boiling is the maximum temperature a substance can reach.
  25. Ice cannot change temperature.
  26. Objects of different temperature that are in contact with each other, or in contact with air at different temperature, do not necessarily move toward the same temperature.
  27. Heat only travels upward.
  28. Heat rises.
  29. The kinetic theory does not really explain heat transfer. (It is recited but not believed).
  30. Objects that readily become warm (conductors of heat) do not readily become cold.
  31. The bubbles in boiling water contain "air", "oxygen" or "nothing", rather than water vapor.
