  16. 3x500 Describe an experiment to find out the specific heat of brass. BACK

  17. 4x100 Celsius at which water freezes BACK

  18. 4x200 What is happening to the temperature in this graph? BACK

  19. 4x300 Temperature is a measure of the average __________ BACK

  20. 4x400 Daily Double Kelvin at which water boils BACK

  21. 4x500 What happens to the molecules when the temperature decreases? BACK

  22. 5x100 Ms. Al-Khalifa’s water reached 100 degrees Celsius but its not boiling why? BACK

  23. 5x200 Ms. Al-Khalifa is trying to cook meat for her family using a pot but it takes a very long time and needs to add water many times as it evaporates very quickly. What can she use to help make her cooking time less and more easier? Why? BACK

  24. 5x300 Ms. Al-Khalifa traveled to Alaska for a 3 month training course. She is starting her car but its not running. The repair man told her she forgot to put antifreeze in her car engine. Why is that important? BACK
