1. The vapor pressure of water at 25C is 23.76 torr. If 1.25g of water is enclosed in a 1.5L container, will any liquid be present? If so, what mass of liquid? 2. Draw a heating curve (such as the one in Figure 12.36) for 1 mole of methanol beginning at 170K and ending at 350K. Assume that the values given here are constant over the relevant temperature ranges. 3. The heat of combustion of CH4 is 890.4 kj/mol, and the heat capacity of H₂0 is 75.2 J/molK. Find the volume of methane measured at 298K and 1.00 atm required to convert 1.00L of water at 298 K to water vapor at 373K. 4. Suggest an explanation for the observation that the heat of fusion of a substance is always smaller than its heat of vaporization.
