Question

the ____ must be collected in order to determine the caloric content of food using a bomb calorimeter. change in volume of water lost change in water temperature change in water weight the rate at which food burns

Explanation:

A bomb calorimeter measures heat released by a combustion reaction. The heat released is absorbed by water in the calorimeter. According to the principle $q = mc\Delta T$ (where $q$ is heat, $m$ is mass of water, $c$ is specific - heat capacity of water, and $\Delta T$ is change in temperature), the change in water temperature is used to calculate the heat released, which is related to the caloric content of the food.

Answer:

change in water temperature
