(10%) Problem 1: A monatomic ideal gas initially fills a $V_o = 0.35 \text{ m}^3$ container at $P_o = 95 \text{ kPa}$. The gas undergoes an isobaric expansion to $V_1 = 1.4 \text{ m}^3$. Next it undergoes an isovolumetric cooling to its initial temperature $T_o$. Finally it undergoes an isothermal compression to its initial pressure and volume. ?10% Part (d) Write an expression for the change in internal energy, $\Delta U_1$ during the isobaric expansion (first process). 10% Part (e) Calculate the work done by the gas, $W_2$, in kilojoules, during the isovolumetric cooling (second process). $W_2 = 0.000$ ? Correct! ?10% Part (f) Calculate the heat absorbed $Q_2$, in kilojoules, during the isovolumetric cooling (second process). ?10% Part (g) Calculate the change in internal energy by the gas, $\Delta U_2$, in kilojoules, during the isovolumetric cooling (second process). ?10% Part (h) Calculate the work done by the gas, $W_3$, in kilojoules, during the isothermal compression (third process). ?10% Part (i) Calculate the change in internal energy, $\Delta U_3$, in kilojoules, during the isothermal compression (third process). ?10% Part (j) Calculate the heat absorbed $Q_3$, in kilojoules, during the isothermal compressions (third process).
