A500-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 bottle of water had cooled to the temperature of the refrigerator. an hour later, the 2-l of water had cooled to the same temperature. when asked which sample of water lost the most heat, one student replied that both bottles lost the same amount of heat because they started at the same temperature and finished at the same temperature. a second student thought that the 2-l bottle of water lost more heat because there was more water. a third student believed that the 500-ml bottle of water lost more heat because it cooled more quickly. a fourth student thought that it was not possible to tell because we do not know the initial temperature and the final temperature of the water. indicate which of these answers is correct and describe the error in each of the other answers.
