A calorimeter is used to measure the amount of energy in foods. The following features lead to more reliable results:
  1. The food is ignited electronically
  2. The food burns in oxygen and therefore burns completely without leaving a mass of carbon
  3. The combustion chamber is surrounded by water so little or no heat energy is lost from the system
  4. The stirrer leads to more efficient heat transfer and ensures that the water is of an even temperature.
