Question
Use data in Appendix $\mathrm{E}$ to calculate the amount of heat required to warm $170 . \mathrm{g}$ of mercury from $25^{\circ} \mathrm{C}$ to its boiling point and then to vaporize it.
Step 1
The specific heat capacity of mercury is 0.14 J/g°C (from Appendix E). The boiling point of mercury is 357°C (from Appendix E). The mass of mercury is 170 g. We can use the formula for heat transfer: q = mcΔT, where q is the heat transfer, m is the mass, c is Show more…

Use data in Appendix $E$ to calculate the amount of heat required to warm $165 . \mathrm{g}$ of mercury from $25^{\circ} \mathrm{C}$ to its boiling point and then to vaporize it.
Use the following data and data from Appendix D to determine the quantity of heat needed to convert $15.0 \mathrm{g}$ of solid mercury at $-50.0^{\circ} \mathrm{C}$ to mercury vapor at $25^{\circ} \mathrm{C} .$ Specific heats: $\mathrm{Hg}(\mathrm{s}), 24.3 \mathrm{Jmol}^{-1} \mathrm{K}^{-1} ; \mathrm{Hg}(1)$ $28.0 \mathrm{Jmol}^{-1} \mathrm{K}^{-1} .$ Melting point of $\mathrm{Hg}(\mathrm{s}),-38.87^{\circ} \mathrm{C}$ Heat of fusion, $2.33 \mathrm{kJ} \mathrm{mol}^{-1}$..
Use data from Appendix D to estimate (a) the normal boiling point of mercury and (b) the vapor pressure of mercury at $25^{\circ} \mathrm{C}$.
