The boiling point of a liquid is the temperature at which the vapor pressure of a liquid equals the external pressure acting on its surface. For this reason, the water boils at lower temperature at higher altitudes. This is an important concept for chemical, nuclear, and other engineers engaged in processes dealing with boiling liquids. Data on the vapor pressure P of water as a function of temperature T is given in the following table. Theoretically, the pressure P is inversely proportional to the absolute temperature T. Obtain a curve fit for p(T) for the given data and use this fit to estimate the vapor pressure at 285K and 300 K.
