The issues here depends upon the definition of boiling point of a liquid phase substance. However, if one is considering the boiling point values of substances in terms of their chemical and physical properties, the Boiling Points are inversely dependent upon the vapor pressure exhibited by a liquid phase substance at a specified temperature. Solving this expression for #T_2 => 371K = BP_2# The Clausis-Clapeyron Equation is derived from #VP_2 = VP_1e^(-DeltaH_v/(RT))# at two different temperatures. If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. If a specified substance is subjected to variations in surrounding atmospheric pressures, the Boiling Points will decrease with decreasing atmospheric pressure values and Increase with increasing atmospheric pressure values.
