Suspension

In general, suspension refers to a state in which small solid particles remain suspended in a fluid (liquid or gas) and do not settle quickly due to the force of gravity.

Factors affecting suspension stability

Particle size: Smaller particles tend to remain suspended due to their greater contact surface with the fluid.
Particle and fluid density: The smaller the density difference between the particles and the fluid, the more stable the suspension.
Fluid viscosity: Increasing fluid viscosity reduces the rate at which particles settle.
Additives: Additives such as emulsifiers can help stabilize the suspension.
