## Starting from the Clapeyron equation, derive the Clausius-Clapeyron equation. Be sure to state any approximations that you make. On the surface of Mars, water boils at 276K. Given that the enthalpy of vaporization of water is 40.66 KJ mol^-1, what is the atmospheric pressure on the surface? (At P = 1 bar, water boils at 373 K.)
