7.2. Calculate the total surface energy of a 5 g emulsion of benzene in water with a concentration of 75% (mass) and dispersion D = 2 µm-1 at a temperature of 313 K. The density of benzene at this temperature is 0.858 g/cm3, surface tension σ = 32.0 mJ/ m2, temperature coefficient of surface tension of benzene dσ /dT= 0.13 mJ/(m2 K).
