Measurement of the

True Specific Heat of Nickel by a Direct Electrical Method. Miss CH. LAPP. (Comptes Rendus, April 23, 1928.) Measurements were made on pure nickel for temperatures ranging from -175 ° to + 460 °. A nickel wire is put in a furnace whose temperature is kept uniform. For a part of a minute an electric current is sent through the wire the temperature of which is thereby raised one or two degrees. The temperature is obtained from a thermoelectric couple and the time is registered by a chronograph. From the use of these data supplemented by the energy furnished by the current to the wire it is possible to compute the specific heats at different temperatures. Temperature -175 ° +10 ° 339 ° 350 ° 352.2 ° 352.8 ° 353.8 ° 360 ° 460 ° Specific Heat .
