In the problems below the equation for equilibrium (saturation) vapor pressure as a function of temperature may be useful. This equation, also known as the Clausius-Clapeyron relation, is P#(T)= p#(T,)eR, To For calculations you can use the triple point T, = 273 K, the "latent heat of vaporization" L, = 2.25 x 10° J/kg (in reality it changes a bit with temperature), the gas constant for water vapor R, = 461.5 J/kg, and p*(T,) = 6.1 hPa.
