Consider an ideal gas undergoing a constant pressure process from state 1 to state 2 in a closed system. The specific heat capacities for this material depend on temperature in
the following way, cv = aT^b , cp = cT^d , where the constants a, b, c and d are known. Calculate

the specific entropy change, (s2 − s1), from state 1 to state 2.

Explanation:

Hello,

In this case by combining the first and second law of thermodynamics for this ideal gas, we can obtain the following expression for the differential of the specific entropy at constant pressure:

Whereas Rg is the specific ideal gas constant for the studied gas; thus, integrating:

We obtain the expression to compute the specific entropy change:
