Start with equation (8.19b) for the change in entropy:
$s_2 - s_1 = R \ln \left\{ \left( \frac{T_2}{T_1} \right)^{\frac{\gamma}{\gamma - 1}} \left( \frac{P_1}{P_2} \right) \right\}$
Show the following 2 relations:
$s_2 - s_1 = c_p \ln \frac{T_2}{T_1} - R \ln \frac{P_2}{P_1}$
$s_2 - s_1 = c_v \ln \frac{T_2}{T_1} + R \ln \frac{V_2}{V_1}$

Step 1

19b) for the change in entropy: Δs = Rln(V2/V1) Step 2: Recall the ideal gas law, which states that PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. Step 3: Rearrange the ideal gas law to solve for Show more…
