👉 The dependent fluid, also known as a colloid, is a type of fluid where the dispersed particles are larger than those in a solution but smaller than those in a suspension, typically ranging from 1 to 1000 nanometers. These particles remain suspended in the fluid due to Brownian motion and electrostatic repulsion, preventing them from settling out as they would in a suspension. This unique property allows dependent fluids to exhibit characteristics of both liquids and suspensions, such as stability and resistance to sedimentation. Examples include milk (containing fat droplets), blood (with red blood cells), and fog (water vapor suspended in air).
