    In the vicinity of the triple point, the equation of the liquid-vapour boundary in the P-V (pressure-volume) phase diagram is given by the Clausius-Clapeyron equation. This equation relates the pressure and temperature at which the liquid and vapor phases coexist:

    ln(P2/P1) = ΔHvap/R * (1/T1 - 1/T2)

    where P1 and P2 are the pressures at two different temperatures T1 and T2, ΔHvap is the enthalpy of vaporization, R is the ideal gas constant, and ln is the natural logarithm.

    The Clausius-Clapeyron equation describes the relationship between the pressure and temperature at which a substance undergoes a phase transition between the liquid and vapor phases. In the vicinity of the triple point, where all three phases (solid, liquid, and vapor) coexist in equilibrium, the equation can be used to determine the conditions under which the liquid and vapor phases are in equilibrium.

    It is important to note that the Clausius-Clapeyron equation is an approximation and may not be valid for all substances and conditions. It assumes that the enthalpy of vaporization is constant over the temperature range of interest and that the vapor behaves ideally. However, deviations from ideality and variations in the enthalpy of vaporization with temperature can occur, especially at extreme conditions.
