Abstract
IT is possible to measure the specific heat of a liquid at a number of different temperatures by determining the power required to hold the temperature of a calorimeter and its contents stationary at different temperatures above that of the surroundings. The power is supplied electrically to a coil immersed in the liquid, and we have If a cooling curve is now taken, it can be shown that within the limits of experimental error, where n is nearly, but not exactly, equal to 5/4, K and n being determined by the use of a least-square or some equivalent method. We thus have giving the specific heat s in terms of the 20° calorie, if an experiment be performed with water at 20° C.
