Solution:
\textbf{True or False. If your answer is “false”, you must justify your answer.}
\begin{parts}
\part [5] Diesel engine is a heat engine and it converts work into heat.
\part [5] The entropy change of a system cannot be negative.
\part [5] For a pure species of one mole of a closed system, a reversible phase change when two phases are in equilibrium, then $T \Delta S = \Delta H$.
\part [5] $\overline{V}_i^{id} = V_i^{id}$
\part [5] A mass of $500\ g$ of gaseous ammonia is contained in a $30,000\ cm^3$ vessel immersed in a constant–temperature bath at $65^\circ C$. If you are required to calculate the pressure of the gas by using “Pitzer correlations for the second Virial coefficient”, you must guess an initial pressure value. Thus, by trial and error, you can obtain an approximate solution for pressure.
\part [5] $\Delta H = Q$ is not only valid for the closed systems of constant pressure, it is also valid for flow systems under certain assumptions.
