HeatCapacityin Calorimetryformulais defined as the quantity ofheatabsorbed by thecalorimeterfor each 1°C rise in temperature and is represented as C = Q/Δθ orHeatCapacity=Heat/Difference in Temperature.heatcapacityis theheatcapacityper unit amount (SI unit: mole) of a pure substance, and the specificheatcapacity, often called simply specificheat, is theheatcapacityper unit mass of a material.Heatcapacityis a physical property of a substance, which means that it depends on the state and properties of the substance under ...heat. Once you become familiar with the terms used for calculating specificheat, you should learn the equation for finding the specificheatof a substance. Theformulais: C p = Q/mΔT. You can manipulate thisformulaif you want to find the change in the amount ofheatinstead of the specificheat.heatcapacityofacalorimeter, put q = -18.49 kJ and T = (27.93 °C - 26.74 °C) in the equation (ii) 18.49 kJ = c × (27.93 - 26.74) c = 18.49 kJ/1.19 °C c = 15.54 kJ/°C Q14. A 0.500 g sample of naphthalene (C10H8) is burned in a bombcalorimetercontaining 650 grams of water at an initial temperature of 20.00ºC.
