Product description
Calculate the total surface energy of 5 g of an orange oil emulsion in water with a concentration of 55% (mass) and a dispersion of 3 μm-1 at a temperature of 313 K. The density of orange oil is 0.848 g / cm3, interfacial tension is 26.13
mJ / m2, temperature coefficient of surface tension dσ / dT = - 0.13 mJ / (m2 • K).
