Estimate the triple point pressure and teperature of water, given that the standard enthalpies of fusion and vaporization are 6008 J/mol and 43990 J/g at 273.15 K and 298.15 K, repectively, the vapor pressure of water at 25 degress C is 23.8 torr, and making suitable approximations to the Clapeyron equation to solve the problem.
