Draw a heating curve (such as the one in Figure 11.33) for 1 mole of methanol beginning at 170 K and ending at 350 K. Assume that the values given here are constant over the relevant temperature ranges.
Added by Patrick C.
Step 1
First, we need to identify the phase transitions for methanol. The melting point of methanol is 175.61 K, and the boiling point is 337.69 K. So, we have three regions in our heating curve: solid, liquid, and gas. Show more…

Use the following data to sketch a heating curve for one mole of methanol. Start the curve at $-100^{\circ} \mathrm{C}$ and end it at $100^{\circ} \mathrm{C}$. $$\begin{array}{ll}\hline \text { Boiling point } & 65^{\circ} \mathrm{C} \\\hline \text { Melting point } & -94^{\circ} \mathrm{C} \\\hline \text { Heat of vaporization } & 35.3 \mathrm{kJ} / \mathrm{mol} \\\hline \text { Heat of fusion }\left(\Delta \mathrm{H}_{\text {fus }}\right) & 3.18 \mathrm{kJ} / \mathrm{mol} \\\hline \text { Molar heat capacity }(\ell) & 81.1 \mathrm{J} /\left(\mathrm{mol} \cdot^{\circ} \mathrm{C}\right) \\\hline \text { Molar heat capacity }(g) & 43.9 \mathrm{J} /\left(\mathrm{mol} \cdot^{\circ} \mathrm{C}\right) \\\hline \text { Molar heat capacity }(\mathrm{s}) & 48.7 \mathrm{J} /\left(\mathrm{mol} \cdot^{\circ} \mathrm{C}\right) \\\hline\end{array}$$
