It is pointed out that in a Ben-Amotz in a recent article [J. Chem. Phys.123, 184504 (2005)] attributed a noncorrect meaning to the entropy convergence temperature, claiming that the latter corresponds to the temperature at which the hydration entropy of a series of solutes crosses zero. A short resumé of the entropy convergence phenomenon and of the provided statistical mechanical analyses is accomplished. In addition, it is brought out that the different temperature dependence of the cavityentropy change on increasing the cavity diameter, pointed out by Ben-Amotz, originates from the assumption that the work of cavity creation should be proportional to the experimental surface tension of liquidwater for cavities large on a molecular scale.
