Abstract:

A precision rotating-bomb combustion calorimeter in which thermistors were used as elements of temperature control and temperature measurement was constructed in our laboratory. The calorimeter was calibrated with benzoic acid of purity 99.999 percent. The energy equivalent of standard calorimeter system is 18.6376±0.0022 kJ.K~(-1). The precision of the experiment was 0.012% (shown in the form of 2s.d m) Detailed Washburn correction was made in microcomputer with programme designed by ourselves.
