The calorimeter constant for a certain constant-volume calorimeter was determined to be 69.3J*K-1. By how much will the temperature rise when 0.01350g of phenol, C6H5OH (s), is burned in the calorimeter? This calorimeter uses 2000g of water (Mm(H2O) = 18.02g*mol-1).
DeltafH(CO2, g) = -393.51 kJ *mol-1 ; delta fH(H2O, l) = -285.83 kJ*mol-1 ; delta fH (C6H5OH, s) = -165 kJ*mol-1 ; Cp.m (H2O) = 75.48 J*mol-1.

A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.4395 g sample of biphenyl (C12H10) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.064×103 g of water. During the combustion the temperature increases from 26.33 to 29.52 °C. The heat capacity of water is 4.184 J g-1°C-1. The heat capacity of the calorimeter was...

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 0.425-g sample of diphenylacetylene (C14H10) in a bomb calorimeter containing 1170. g of water. The temperature increases from...
