between a liquid and its vapor. Heats of vaporization are calculated 

 from this formula. 



(e) The formula is inapplicable in cases where the specific heat at 

 constant volume differs in the liquid and gaseous state. A method of 

 calculating these specific heats is given. 



(y ) The formula applies perfectly in the case of mercury. 



{g) The vapor pressure curve is discussed. 



III. (a) Application of the general equations to solutions leads to 

 simple expressions for osmotic pressure and osmotic work in concentrated 

 solutions. 



(h) Equations are given for the distribution of a solute between two 

 solvents, and for the relation between the solubility curves of a substance 

 in different solvents. 



IV. The influence of the nature of the solvent upon general homoge- 

 neous equilibrium is determined and formulas are given. 



V. («) The general equation for free energy is applied to electro- 

 chemistry. For the single potential difference between a metal and an 

 electrolyte an equation is proposed which is an amplification of the equa- 

 tion of Nernst. 



(6) Galvanic cells in which two solvents take part are discussed.
