A bomb calorimeter, or constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. Since the "bomb" itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter. In the laboratory a student burns a 0.466-g sample of 1,8-octanediol (C8H18O2) in a bomb calorimeter containing 1200. g of water. The temperature increases from 25.90 °C to 28.70 °C. The heat capacity of water is 4.184 J g-1°C-1. The molar heat of combustion is −5094 kJ per mole of 1,8-octanediol. C8H18O2(s) + 23/2 O2(g) 8 CO2(g) + 9 H2O(l) + Energy Calculate the heat capacity of the calorimeter. heat capacity of calorimeter = ____J/°C

In an adiabatic, constant-volume bomb calorimeter, a combustion
of 0.7362g of naphthalene (C10H8) caused the temperature to rise of
5.707 Celcius. The final temperature was 298.000K. The heat
capacity of the calorimeter, Ccal was 10290 J/K . (Note: this value
of Ccal includes the contribution from water.) The molar enthalpies
of formation of CO2(g) and H2O(l) are: -393.522 kJ/mol, -285.830
kJ/mol, respectively Mm(C)= 12.01 g/mol and Mm(H)= 1.001 g/mol.

In the laboratory a"coffee cup" calorimeter, or constant
pressure calorimeter, is frequently used to determine the specific
heat of a solid, or to measure the energy of a solution phase
reaction. A student heats65.62grams ofzincto98.24 °C and then drops
it into a cup containing75.87grams of water at23.87 °C. She
measures the final temperature to be29.24 °C. The heat capacity of
the calorimeter (sometimes referred to as thecalorimeter constant)
was determined in a separate experiment to be1.54J/°C. Assuming
that no heat...
