Final answer:
The enthalpy of vaporization (ΔHvap) of a liquid can be calculated using the Clausius-Clapeyron equation, which relates the vapor pressure of a substance at two different temperatures to its enthalpy of vaporization.
Step-by-step explanation:
The Vapor Pressure of a liquid is the pressure exerted by its vapor in equilibrium with its liquid phase at a given temperature.
The Clausius-Clapeyron equation can be used to relate the vapor pressure of a substance at two different temperatures to its enthalpy of vaporization (ΔHvap).
The equation is:
ln(P₂/P₁) = -ΔHvap/R * ((1/T₂) - (1/T₁))
Where P₁ and T₁ are the vapor pressure and temperature at one point, and P₂ and T₂ are the vapor pressure and temperature at another point. By rearranging the equation and solving for ΔHvap, we can calculate the enthalpy of vaporization for the given liquid.
