It can be seen that the interaction energy between anions and cations in the ionic liquid decreases after the addition of the co-solvent. New hydrogen bonds are formed between the co ... WebThe viscosity of liquids decreases with temperature, whereas the viscosity of gases increases with temperature. This is because in a liquid the molecules possess more energy at higher temperatures, and they can oppose the large cohesive intermolecular forces more strongly. As a result, the energized liquid molecules can move more freely. WebAnother important rheological value in the cosmetics industry is the pour point. Some liquids behave like inert solids but flow like a liquid. When the yield value or pour point is exceeded, the viscosity decreases. Liquids with high yield points can easily suspend particles such as pigments in cosmetic preparations. ctfshow misc 30
