Solid and dotted lines denote chemical potentials for 3 phases at P = P 0 and P 0 + Δ P, respectively. Q1. This molecule satisfies (choose one) (a) V m, Solid > V m, Gas > V m, Liquid (b) V m, Gas > V m, Liquid > V m, Solid (c) V m, liquid > V m, Gas > V m, Solid (d) V m, Gas > V m, Solid > V m, Liquid Q2. What does T D in the figure 1 mean? a) Melting point of X at P = P 0 b) Melting point of X at P = P 0 + Δ P c) Boiling point of X at P = P 0 d) Boiling point of X at P = P 0 + Δ P Q3. Figure 2 shows the temperature dependence of chemical potential for molecule Y in 3 different phases. What does the black dot indicate? Choose the most suitable word . a) triple point b) sublimation point c) melting point. d) critical point e) boiling point Q4. We calculated Δ G for two compression processes of 2.00 mol of an ideal gas at 298 K from an initial pressure of 1.0 bar to a final pressure of 12.0 bar.
