cze	Tepelná kapacita, entalpie a entropie Li2CO3 od 303.15 do 563.15 K	Tepelná kapacity uhličitanu litného byla měřena na kalorimetru s tepelným tokem za atmosférického tlaku pro teploty od 303.15 do 563.15 K. Teplotní závislost tepelné kapacity pro tento interva je Cp [J mol-1.K-1] = 92.80 + 0.09T - 1.91 x 106T-2. Změna entalpie a entropie vztažená k referenční teplotě 298.15 K pro stejný teplotní inervel je HT - H298 [kJ mol-1] = -48.92 + 0.14T + 6.68 x 105T-2 ST - S298 [J mol-1K-1] = -53.73 + 0.24T - 1.55 x 106T-2.	tepelná kapacita;uhličitan litný;entalpie;entropie;kalorimetrie
eng	Heat Capacity, Enthalpy and Entropy of Li2CO3 at 303.15 to 563.15 K	Measurements of the heat capacity of lithium carbonate were carried out with a heat conduction calorimeter in the temperature range of 303.15 to 563.15 K at atmospheric pressure. The temperature dependence of the heat capacity is Cp [J mol-1.K-1] = 92.80 + 0.09T - 1.91 x 106T-2. The thermodynamic functions with reference temperature 298.15 K, calculated in the same temperature range are HT - H298 [kJ mol-1] = -48.92 + 0.14T + 6.68 x 105T-2 ST - S298 [J mol-1.K-1] = -53.73 + 0.24T - 1.55 x 106T-2.
