Homework Help: Clausius Claperon Equation

  1. Feb 7, 2012 #1
    1. The problem statement, all variables and given/known data
    cal the boiling point of water at 300m. assume its 100 degree centigrade at sea level. given g, R, T=300K, molecular weight of air is 29g/mol and latent heat of evaporation is 540 cal/g at STP

    2. Relevant equations
    The equation is

    dp/dt= L/T(v2-v1)

    where v is the specific volume of water at temp 1 and temp 2

    3. The attempt at a solution
    i was able to calcutale dp as it ρgh. i m stuck what to do with v2-v1 part

    Consider the relative numbers involved with v2 vs. v1. Simplify the equation accordingly.

    Then think about the ideal gas law.
