During digestion, the energy in food is converted to energy the body can use. Scientists use calorimetry experiments to measure the calories, or energy, provided by food when it is digested or burned.
The relationship used to find the heat transferred energy is given by
, where
is the mass of the material,
is the given specific heat capacity, and
is the change in temperature of the material.
In this experiment, food was burned over a Bunsen burner under a can of 200 ml of water. The temperature change of the water and mass change of the food can be used to determine the calories in four different food items.
Table 1 shows the values of the change of mass of the food items, the change in temperature of the water and the energy. Table 2 shows the energy to mass ratio of three of those food items.

Based on the information in Table 1, what variables must be measured in order to calculate the energy of the food samples?
Change in mass of the food and change in temperature of the water
Change in mass and temperature of the water
Change in temperature of the water alone
Change in mass of the food sample alone
Based on the given equation for calculating heat energy, the heat capacity of the water, change of mass of the material, and change in temperature of the material must be measured. However, because the heat capacity of water is consistent, it does not affect the measure of the different calorie measurements. Additionally, because the change in heat of the food samples must approximately equal the change in temperature of the food item due to their proximity, only the change in temperature of the water and change in mass of the food samples needs to be known. Also, this answer is given in the description of the experiment.
