Case II Temperature-Dependent Specific Heat Values

2 Case II Temperature-Dependent Specific Heat Values 

With the substitution of the functional relations for specific heats, these equations can be evaluated by carrying out the integration term by term. 

Using the procedure outlined for enthalpy, the integral equation (Equation 3.55b) is written by computing entropy change from a reference temperature as follows  

The integral given by Equation 3.48 is evaluated for different gases over a range of temperatures and assuming a reference temperature of Tq = 20°C or 298 K. Table C.7 presents such integral values for some of the common ideal gases.
