The heat required to raise the temperature of m (kg) of a liquid from T1 to T2 at constant pressure is: -T2 Cp dT AH = m Q = In first year, you saw the equation Q = mCpAT What assumption about Cp is required to go from the first equation to the 2nd? a) b) The heat capacity (Cp) of liquid n-hexane is measured in a bomb calorimeter. A small flask (the bomb) is placed in a well-insulated vessel containing 2L of liquid n-hexane at 300K. A combustion reaction releasing 16.73KJ of heat takes place in the bomb, and the subsequent temperature rise of the system contents is measured and found to be 3.10K. In a separate experiment, it is found that 6.14 kJ of heat is required to raise the temperature of everything in the system except hexane by 3.10K. Use this data to calculate Cp (kJ/mol-K) for liquid n-hexane at 300K assuming that the condition listed in a) is valid. The density of hexane is 659 g/L.
