2. Suppose thal $1.15\mathrm{g}$ of rubbing alcohol $\left({\mathrm{C}}_3{\mathrm{H}}_8\mathrm{O}\right)$ evaporates from a $65.0\mathrm{g}$ aluminum block. If the aluminum block is initially at $25^{\circ }\mathrm{C}$, what is the final temperature of the block after the evaporation of the alcohol? Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at $25^{\circ }\mathrm{C}.\Delta H_{\text{vap }}=39.9\mathrm{kJ}/\mathrm{mol};\mathrm{CAl}=0.903\mathrm{J}/{\mathrm{g}}^{\ast \circ }\mathrm{C}$ 3. This table displays the vapor pressure of nitrogen at several different temperatur Use the data to determine the heat of vaporization and normal boiling point of nitrogen.
