The energy content of a certain food is to be determined
Chapter 4, Problem 125P(choose chapter or problem)
The energy content of a certain food is to be determined in a bomb calorimeter that contains \(3 \mathrm{~kg}\) of water by burning a \(2-\mathrm{g}\) sample of it in the presence of \(100 \mathrm{~g}\) of air in the reaction chamber. If the water temperature rises by \(3.2^{\circ} \mathrm{C}\) when equilibrium is established, determine the energy content of the food, in \(\mathrm{kJ} / \mathrm{kg}\), by neglecting the thermal energy stored in the reaction chamber and the energy supplied by the mixer. What is a rough estimate of the error involved in neglecting the thermal energy stored in the reaction chamber?
