Question

Почему частицы порошка не опускаются на дно?????

Answer 1

Why don't particles of powder sink to the bottom?

The reason why particles of powder do not sink to the bottom is due to a phenomenon called suspension. When a powder is mixed with a liquid, the particles of the powder become dispersed throughout the liquid instead of settling at the bottom. This is because the particles are small and light enough to be suspended in the liquid, and they are constantly moving due to the random motion of the liquid molecules.

The suspension of particles in a liquid is influenced by several factors, including the size and density of the particles, the viscosity of the liquid, and the agitation or stirring of the mixture. If the particles are too large or too dense, they may settle at the bottom more quickly. Similarly, if the liquid is very viscous or if the mixture is not agitated, the particles may have a higher tendency to settle.

It's important to note that the specific behavior of particles in a powder and liquid mixture can vary depending on the properties of the powder and the liquid involved. Different powders may have different particle sizes, densities, and surface properties, which can affect their suspension in a liquid. Additionally, the viscosity of the liquid and the presence of other substances in the mixture can also influence the behavior of the particles.
