HEAT CAPACITIES. TRUE AND MEAN SPECIFIC HEATS. AND 



LATENT HEATS AT FUSION- 



225 



The following data are taken from a research and discussion entitled "Die Temperatur- 

 Warmeinhaltskurven der technisch wichtigen Metalle," Wiist, Meuthen und Durrer, For- 

 schungsarbeiten herausgegeben vom Verein Deutscher Ingenieure, Springer, Heft 204, 1918. 



(a) There follow the constants of the equation for the heat capacity: W = a + bt + ct^; for 

 the mean specific heat: 5 = at'^ + b +ct; and for the true specific heat: s' = b + 2cl; also the 

 latent heats at fusion. (See also Table 243, pp. 223-224.) 



*Allotropic heat of transformation: Mn, 1070-1130°; Ni, 320-330°; Co, 950-1100°; Fe, 

 725-785°; 919° =<= i; 1404-5° =^ 0.5.
