Publisher's Synopsis
Excerpt from Specific Heat of Some Calcium Chloride Solutions Between -35� C and ]20� C
In operation, the calorimeter (c) is kept at the same tempera ture as the surrounding vessel, equality being shown by means of the copper-constantan thermocouple (tc) connected directly to a sensitive galvanometer. Differences of temperature not exceed ing one or two tenths of a degree may occur, and a calibration of the thermocouple enabled a correction to be made for them.
The centrifugal propeller (p) is driven by a belt from a small motor and the speed kept constant by a friction governor on the motor.
