👉 A particle fluid, also known as a colloid, is a mixture where particles are dispersed in a continuous medium, typically a liquid or gas, but not fully dissolved as in a solution. These particles range in size from 1 to 1000 nanometers, larger than molecules but smaller than colloidal particles. Due to their intermediate size, particle fluids exhibit unique properties such as the Tyndall effect (scattering of light), higher viscosity compared to solutions, and the ability to settle over time if not stabilized by particles, surfactants, or other means. This makes them distinct from true solutions and suspensions, where particles are either dissolved or remain larger and settle more quickly.
