Lab 11B: Calories in Food Lab

Question 1: We measured the change in temperature in the water above the calorimeter. We put the calorimeter over the food sample that was burning and then we put a flask of water on top of it. This way we could measure the temperature easily with the thermometer we were provided.

Question 2: We measured the energy gained by the water because the temperature of the water measures the energy gained by it.

Question 3: The small amount of energy that does not go into the water will go into the surroundings, or in this case the can and air around the experiment.

Question 4: I was surprised that the cheese puff burned very fast and then did not burn easily. I was also surprised that the pecan had the most calories of all the foods tested.
