|A common misconception: Many students believe heat and temperature are the same thing.
A question probing this misconception: A 500-mL bottle of water at room temperature and a 2-L bottle of water at the same temperature were placed in a refrigerator. After 30 minutes the 500 mL of water had cooled to the temperature of the refrigerator. Two hours later the 2 L of water had cooled to the same temperature. Did one sample of water lose more heat than the other?
- The 2 L of water lost more heat because there was more water.
- The 500 mL of water lost more heat because it cooled more quickly.
- Both bottles lost the same amount of heat because they started at the same temperature and finished at the same temperature.
- It is not possible to tell because we do not know the initial temperature and the final temperature of the water.
