Heat capacities of gibbsite, Al(OH)3, between 13 and 480 K and magnesite, MgCO3, between 13 and 380 K and their standard entropies at 289.15 K, and the heat capacities of Calorimetry Conference benzoic acid between 12 and 316 K
November 1, 1977
The heat capacities of gibbsite and magnesite were measured between 13 and 380 K by means of an adiabatic calorimeter. The heat capacity of gibbsite was measured continuously between 340 and 480 K by means of a differential scanning calorimeter. Tables of the thermodynamic functions C°P, (H°T–H°O)/T,–(G°T–H°O)/T, and S°T–S°O are presented for these phases at integral temperatures. S°T–S°O are 68.44±0.14 J/(K•mol) and 65.09±0.13 J/(K•mol) at 298.15 K for gibbsite and magnesite, respectively. The heat capacities of Calorimetry Conference benzoic acid have been remeasured between 12 and 316 K.
