👉 A took fluid, also known as a colloid, is a mixture where tiny particles are dispersed in a medium but remain suspended due to their size, typically between 1 and 1000 nanometers. Unlike true solutions where particles are completely dissolved at the molecular or ionic level, took fluids consist of larger particles that do not settle out over time, yet they do not exhibit the same clarity as true solutions. This suspension results from forces like van der Waals forces or electrostatic repulsion between particles, preventing them from coalescing. Examples include milk, paint, and fog, where the particles are large enough to scatter light and give the fluid its characteristic properties.
