Question

Седиментационное равновесие?

Answer 1

Действие силы тяжести для коллоидных частиц невелико и уравновешивается броуновским движением и диффузией. Такое состояние называется седиментационным равновесием.
седиментационное равновесие это равномерное распределение частиц по высоте в поле земного тяготения.

Answer 2

Sedimentation Equilibrium

Sedimentation equilibrium refers to a state in which the rate of sedimentation of particles in a fluid is balanced by the rate of diffusion or convection, resulting in a stable distribution of particles based on their size and density. This equilibrium is achieved when the gravitational force acting on the particles is equal to the opposing forces, such as buoyancy or drag forces.

In sedimentation equilibrium, particles settle under the influence of gravity, but their settling is counteracted by other forces that prevent them from continuously settling to the bottom. These forces can include the buoyant force exerted by the fluid, which depends on the density difference between the particles and the fluid, as well as the drag force caused by the fluid's viscosity.

Key Points: - Sedimentation equilibrium occurs when the rate of sedimentation is balanced by opposing forces. - The gravitational force, buoyant force, and drag force play important roles in achieving sedimentation equilibrium.

Sedimentation equilibrium is commonly used in various scientific and industrial applications, such as particle size analysis, purification of biological macromolecules, and separation of particles based on their size and density. By studying the sedimentation behavior of particles, scientists can gain insights into their physical properties and interactions.
