When scientists use a device called a calorimeter, the prece of food to be measured is placed inside the device, sealed, and then burned, the energy from the food heats the water surrounding the chamber. by weighing the amount of water heated, nothing the increase in the water temperature, and multiplying the two, the energy capacity of the food can be measured. for example, if 10 liters of water surrounding the chamber is 20 degrees centigrade before combustion and then is measured at 25 degrees after combustion, the difference in temperature is multiplied by the volume of water to arrive at the caloric value.1. the energy capacity of food
