A 0.8kg of a perfect gas has R = 0.274 kJ/kg.K, = 1.38, Cv = 0.72 kJ/kg.K and is expanded from a pressure of 9 bar at 23 °C to a pressure of 1.8 bar according to the law PV1.3 = C. Calculate the change in entropy.

Step 1
8 kg - R = 0.274 kJ/kg·K - γ = 1.38 - Cv = 0.72 kJ/kg·K - Process: PV^n = C with n = 1.3 - P1 = 9 bar, T1 = 23°C = 296 K - P2 = 1.8 bar Show more…

0.5 kg of a perfect gas is heated from 100 °C to 300 °C at a constant pressure of 2.8 bar. It is then cooled to 90 °C at constant volume. Find the overall change in entropy. Take Cp = 1 kJ/kg and Cv = 0.72 kJ/kg.

The ideal gas in the cylinder in Fig. $21-1$ is initially at conditions $P_{1}, V_{1}, T_{1}$. It is slowly expanded at constant temperature by allowing the piston to rise. Its final conditions are $P_{2}, V_{2}, T_{1}$, where $V_{2}=3 V_{1}$. Find the change in entropy of the gas during this expansion. The mass of gas is $1.5 \mathrm{~g}$, and $M=28 \mathrm{~kg} / \mathrm{kmol}$ for it. Recall from $\underline{\text { Chapter } 20}$ that, for an isothermal expansion of an ideal gas (where $\Delta U=0$ ), $$ \begin{array}{c} \Delta W=\Delta Q=P_{1} V_{1} \ln \left[\frac{V_{2}}{V_{1}}\right) \\ \Delta S=\frac{\Delta Q}{T}=\frac{P V_{1}}{T_{1}} \ln \left(\frac{V_{2}}{V_{1}}\right)=\frac{m}{M} R \ln \left(\frac{V_{1}}{V_{1}}\right) \\ \hline \end{array} $$ where we have used the Ideal Gas Law. Substituting the data leads to $$ \Delta S=\left(\frac{1.5 \times 10^{-3} \mathrm{~kg}}{28 \mathrm{~kg} / \mathrm{kmol}}\right)\left(8314 \frac{\mathrm{J}}{\mathrm{kmol} \cdot \mathrm{K}}\right)(\ln 3)=0.49 \mathrm{~J} / \mathrm{K} $$
