A simple calorimeter constructed from Styrofoam coffee cups, such as you will use in the laboratory, measures reaction heats under constant pressure conditions; thus, q rxn = ΔH rxn, the change in enthalpy of the reaction. This is often used to measure the heat change of a solution formed in the inner cup. Indirect calorimetry measures the amount of heat you produce by determining how much gas (carbon dioxide and nitrogen) you exhale. Because these gases are the end products of the majority of metabolism, it gives a very accurate measurement of how much energy you use in a given period.

"Bomb calorimeter" sounds a bit confusing – it can also be called a "combustion calorimeter." The sample is placed in a small metal container and lit, or combusted, so it burns up. The heat from the sample is transferred to the can and then to the water. The temperature difference of the water is measured from start to finish.
