Superheated liquid water (α phase) exists at 593 K and 1 bar along with a vapor embryo (β phase) at the same temperature. The saturation pressure at 593 K is 133 bar. Determine the size of the embryo bubble assuming that the surface tension σ?=?10.5 ×?10-6 kN m and the liquid molar volume to be 0.018 m3 kmole-1 .
