ABSTRACT
Rheopectic liquids become more viscous over time when shaken, agitated, or stressed. Both ultraviolet and viscosity directly depend on molecular interactions, which are derived by varying the compositions of the liquid mixture. The theme could be applied for developing the lightest liquid filled with foam, air, and high-class surfactants so that the resultant mixtures have the lowest binding forces. Thereby, the formulations could replace the use of temperature- based supercritical liquids. For a Newtonian fluid, the viscosity depends on its composition and temperature but for gases and other compressible fluids, it depends on temperature and varies very slowly with pressure. A magneto rheological fluid, for example, becomes thicker when subjected to a magnetic field, possibly to the point of behaving like a solid. These behave as solids at low stress but flow as viscous fluids at high stress. A magnetorheological fluid, for example, becomes thicker when subjected to a magnetic field, possibly to the point of behaving like a solid.
