Answer #1

The Boiling point of any liquid is the temperature at which the vapor pressure of the liquid equals the external pressure surrounding the liquid.

At T=91.2C on mountain range, the water boils, so the vapor pressure of water is equal to the external pressure.

The enthalpy of vaporization of water is 40.65 KJ/mol . Now placing the given values in the clausis - clapeyron equation--
