To calculate the boiling point of a given substance: Use the Clausius–Clapeyron equation: ln (P₁/P₂) = -ΔH/R × (1/T₁ − 1/T₂) Insert the pressure values at state 1 and state 2, P₁ and P₂. Substitute the value of temperature at the initial state T₁. Insert the values of latent heat of vaporization ΔH and the gas constant R.

The formula is: Corrected Boiling Point = Observed Boiling Point + 0.00012(760 - P)(273 + t) Where: P is the observed atmospheric pressure in mm Hg. t is the observed boiling point in °C. If water boils at 98°C when the barometric pressure is 740 mm Hg, we can use this formula to correct the boiling point to standard conditions.
Nov 30, 2022 · R R — Ideal gas constant, equal to 8.314 J/ (K⋅mol). Let's see how to calculate the boiling point temperature with this formula. Simply substitute the known values, P_1 P 1, P_2 P 2, \Delta H ΔH, R R, and T_1 T 1. Then proceed to clear the boiling temperature at the sate 2, T_2 T 2.

The calculator uses the Clausius-Clapeyron equation to compute the boiling point. This equation illustrates the relationship between pressure and temperature for phase transitions. By knowing the heat of vaporization and the boiling point at standard pressure, the calculator can predict how the boiling point changes with pressure.
