Web0.09499. 1.667. * The unit kJ/kg·K is equivalent to kPa·m ^3 3 /kg·K. The gas constant is calculated from R = Ru /M R = Ru/M, where Ru = Ru = 8.31447 kJ/kmol·K is the universal gas constant and M is the molar mass. Source: Specific heat values are obtained primarily from the property routines prepared by The National Institute of Standards ... WebIf specific heat is expressed per mole of atomsfor these substances, none of the constant-volume values exceed, to any large extent, the theoretical Dulong–Petit limitof 25 J⋅mol−1⋅K−1= 3 Rper mole of atoms (see the last column of this table).
WebIn thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity … WebThe heat capacity at constant volume, Cv, is the derivative of the internal energy with respect to the temperature, so for our monoatomic gas, Cv = 3/2 R. The heat capacity at constant pressure can be estimated because the difference between the molar Cp and Cv is …
