Autograph letter, signed ("A. Einstein"), to Mr. Hans Cassel, Princeton Sept. 24, 1936, in ink on stationary paper measuring 10 7/8 " x 8 1/2" (one page). Einstein writing with formulas that he cannot understand statements relating to Vapor Phase. (Cond: paper shows creases from folding, staining, and age toning, light fading from transfer marks from paperclips) Provenance: Family of Dr. Hans Cassel, Boca Raton, FL (20000/30000)German to English Translation: Princeton Sep. 24, 1936 Dear Mr! I cannot understand your statement for the following reasons. There are two phases present (1 and 2) 2= Vapor-Phase as well as a dissolved substance, which creates an equilibrium between both. It should also be V1 respectively V2 as the specific volume for Unit Mass for the dissolved substance., p1 respectively p2 the particle pressure. If one now makes a circle progress between the two phases with the Unit Mass from the dissolved substance, than as a whole the recorded work is 0. This gives the Formula: V1dp1 = V2dp2 Now you set p2 = p vapor and p1 = p vapor + 2G/R I And you get the equation: V vapor dp vapor = V pd (p vapor + 2G/R) But now I counts for the total pressure from both phases but not for the particle pressure of the dissolved substance, like you predicted. In truth, p1 will be independent from the excess pressure 2G/R, if the Unit Mass is dissolved in the “Liquid” (1) and that does not demand a volume change. Equation I seems totally unfounded and therefore is your beginn
