TABLE 244. 



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 Temperatuiv 

 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 + cf 2 ; for 

 the mean specific heat: 5 = at~ l + b + ct; and for the true specific heat: s' - b + ict\ 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; 9*9 * i; 1404-5 * 0.5. 



(b) TRUE SPECIFIC HEATS.
