Calculate the total surface energy of 8.6 g of an emulsion of benzene in water with a concentration of 75 wt%. and a dispersion of 2 µm-1 at a temperature of 313 K. The density of benzene is p = 0.858 g / ml, surface tension = 32 mJ / m2, temperature coefficient of surface tension of benzene -
(dσ/dT)=-0.13 mJ/m2*K.
