What is the specific heat of ammonium nitrate?
The specific heat is 33.3 cal/degree mol (see below) 1 calorie = 4.18400 joules so specific heat is 139.3272 J/degree mol Molar mass of NH4NO3 is 80.025 g/mol so specific heat is 1.741 J/degree g Physical Properties White crystalline solid; occurs in five different crystallographic modifications as follows: (i) tetragonal form below –18°C (ii) rhombic form between –18 to 32.1°C (iii) rhombic form between 32.1 to 84.2°C (iv) tetragonal form between 84.2 to 125.2° C (v) cubic form between 125.2 to 169.6°C; density 1.725 g/m³ at 20°C; highly hygroscopic; the finely divided powder cakes to a hard mass on storage; melts at 169.6°C; extremely soluble in water; its solubility in 100 g water is as follows: 0°C 118 g 20°C 150 g 40°C 297 g 60°C 410 g 80°C 576 g Dissolution is endothermic, solution becomes cold (and hence its application in freezing bath); elevates the boiling point of water by 1°, 7.5°, 28.5° and 70°C at 10, 40, 80 and 95% (w/w) concentrations, respectively; vapor pressure of sa
