A student used a calorimeter to compare the amounts of energy released by equal samples of onion and garlic. The data from the experiment are shown below. Type of Food Temperature of Water Before Burn?

It seems that the data you intended to provide is incomplete. However, in a calorimetry experiment comparing the energy released by onion and garlic, the student would measure the temperature change of the water before and after burning each food sample. By calculating the difference in temperature and using the specific heat capacity of water, the energy released by each food can be determined. The results can then be analyzed to see which food released more energy.
