Napthalene, C10H8, melts at 80.0°C. If the vapor pressure of the liquid is 10 Torr at 85.8°C and 40 Torr at 119.3°C, and that of the solids is 1 Torr at 52.6°C, calculate a) the AHvap of the liquid, the Tb, and the ASvap at Tb b) the vapor pressure at the melting point c) assuming that the melting-point and triple-point temperature are the same, calculate AHsub of the solid and AHfus.
