✦ Synopsis

An electrically calibrated bomb calorimeter is described which has no stirred water, and is mounted in an evacuated outer jacket. Its departures from the ideal are investigated. The heat of combustion of samples from a batch of specially pure benzoic acid is found to be 26431·7 J/g under ‘standard bomb conditions’, with an estimated standard error of 2·2 J/g. This result is compared with those of conventional calorimeters. Considerably less time per determination is needed with the new calorimeter than with a typical conventional calorimeter.
