Clausius-Clapeyron:
ln(P₂/P₁) = -ΔH/R (1/T₂ - 1/T₁)
R = 8.314 J/(mol·K)
Understanding Boiling Point
The boiling point of a substance is the temperature at which its vapor pressure equals the external pressure. Lower pressure results in a lower boiling point, which is why water boils at lower temperatures at high altitudes.
