Clausius-Clapeyron equatioin's constant for methanol

  1. Jul 4, 2005 #1
    Hi everyone!!
    I'm searching for the constants in Clausius-Clapeyron equation


    I'ld like to know the value of A and C. (for Pressure unity is hPa and Temperature is K )

    They depend on the material under consideration, and on conditions like temperture and pressure. For water you could look at some steam tables. What the equation says is that log P and 1/T are linear as a 1st approximation. The equation can be used to interpolate a data set. Ie you know P(T) for water in 5 K increments from 273 to 373 and want to know P(300.62).
