Description:

This is a technical report on a laboratory experiment determining heating value of fuels. Test sample is naphthalene, and the calibrating substance is benzoic acid. The oxygen bomb calorimeter used is the Parr type.

From the Paper:

"The experiment aims to determine the heat of combustion of naphthalene using data obtained from the Parr bomb calorimeter.
Three 1-g portions of naphthalene were weighed using the analytical balance. Benzoic acid is the calibrating substance used for the experiment. The heat capacity Csys of the system is calculated using the theoretical value of benzoic acid and the nickel fuse wire. This Csys is equivalent to the heat capacity Ccal of the calorimeter; this value will be used in determining the heat of combustion of naphthalene.
The heat of combustion of naphthalene is accepted at
?5156.95 KJ/mol. The experimental value ?3787.445097 KJ/mol has an error of 26.56%."
