PPT-Constant-Pressure Calorimetry

III A 05269 g of octane is placed in a bomb calorimeter known to have a heat capacity of 113 kJ o C The octane a component of gasoline is ignited in the presence of excess oxygen The temperature is increased by 225. Measured values show the thermophysical properties of the examined system or sample There are two bas ic types of calorimeters isothermal and adiabatic Constant temperature is sustained in t he isothermal calorimeter t means that the calorimeter is It operates under the law of conservation of energy (what is that?). Heat loss = Heat gained. A device used to measure the absorption or release of this heat is called . Calorimeter. Watch a video lecture for an example.. Quick Review of Concepts. We have been introduced to heat producing (. exothermic. ) reactions and heat using (. endothermic. ) reactions. Heat is a measure of the transfer of . energy. from a system to the surroundings and from the surroundings to a system. Fall, 2010 Indirect Calorimetry 1 Indirect Calorimetry Indirect Calorimetry CALORIMETRY The science that quantifies the heat release from metabolism is termed calorimetry .
