sedimentation is the tendency for particles in suspension to settle down when there is a stirring in it.this is due to there motion through the fluid in response to the force acting on them
centrifugation is the process of increasing the level of sedimentation by using a centrifuge.
Sedimentation is the process where particles settle down in a liquid due to gravity. Centrifugation involves spinning a sample at high speeds to separate components based on their densities. While sedimentation relies on gravity, centrifugation uses centrifugal force to achieve separation.

What are the methods to separate insoluble solids from liquids?
Filtration, sedimentation, and centrifugation are common methods used to separate insoluble solids from liquids. Filtration involves passing the mixture through a filter medium to trap the solid particles. Sedimentation allows the solid particles to settle at the bottom of the container due to gravity. Centrifugation uses centrifugal force to separate the solid particles from the liquid by spinning the mixture at high speeds.
Why do sawdust in water cannot be separated by sedimentation?
Sawdust in water cannot be separated by sedimentation because sawdust is less dense than water, causing it to remain suspended in the water rather than settling to the bottom. The sawdust particles are too small and lightweight to separate effectively through sedimentation alone. Other methods such as filtration or centrifugation may be more suitable for separating sawdust from water.
How do i separate an insoluble substance?
One way to separate an insoluble substance is by using filtration. By pouring the mixture through a filter, the insoluble substance will be trapped while the soluble substance passes through. Other methods such as sedimentation or centrifugation can also be effective in separating insoluble substances from a mixture.
What is the process of separating a solid from a liquid in a heterogenous mixture?
To separate a solid from a liquid in a heterogeneous mixture, you can use techniques such as filtration or sedimentation. Filtration involves passing the mixture through a filter that traps the solid particles, while sedimentation allows the solid particles to settle at the bottom of the container due to gravity. Once separated, the solid can be collected and the liquid discarded.
What kind of change is needed to separate a mixture into its components?
A physical change is needed to separate a mixture into its components. This can be achieved through processes like filtration, distillation, chromatography, or evaporation, which rely on the differences in physical properties between the components of the mixture.
What is separated by density?
Centrifugation and sedimentation are methods of separation by density.
What are the different methods for separating mixtures?
winnowing,sieving,sedimentation ,centrifugation ,decantation, evaporation
What are the physical method of separation?
Separation methods: filtration, centrifugation, sedimentation, freeze-drying, evaporation, decanting,
What is used to separate the components of a mixture base on densities?
Foe example two methods for liquids: sedimentation and centrifugation.
What is the difference between centrifugation at RPM or g?
Centrifugation at RPM (Revolutions per minute) refers to the speed at which the centrifuge rotor rotates, while centrifugation at g (gravity force) refers to the force applied to the particles in the sample due to the centrifugal force. RPM can be easily converted to g force using a rotor's radius, and both factors influence the sedimentation rate and separation efficiency during centrifugation.

In ribosomes measurement what is the unit 'S'?
'S' stands for Svedberg units, which is a measure of the rate of sedimentation during centrifugation. In ribosomes' case, the 'S' unit indicates their sedimentation rate, which can provide information about their size and shape.
What is the difference between density gradient and differential centrifugation?
Differential centrifugation: The solution (eg sucrose) is uniform throughout the test tube. You separate organelles based on their size and density.Density gradient centrifugation: There is a gradient of concentration of solution throughout the test tube. The concentration of sucrose is minimal at the top of the tube and maximal at the bottom of the tube. This type of centrifugation separates organelles by density only.
What is supertanant liquid?
Supernatant liquid is the liquid portion that remains above a precipitate after centrifugation or sedimentation. It contains the substances that did not precipitate and can be further analyzed or separated from the solid components.
What is zonal centrifugation?
Zonal centrifugation is a technique that separates components in a sample based on their sedimentation rate in a density gradient. The sample is layered on top of the gradient and then subjected to centrifugal force, causing the components to migrate and form distinct bands based on their density. This technique is commonly used to separate and analyze biological molecules based on their size, shape, and density.
How can liquids be separated density?
Liquids can be separated by the density difference by centrifugation.
What Is the difference between sediment and sediment?
in sedimentation there are particles and circumstance that allow these particles sedimented bud in participation there are not any particle and there is a sepration between cations and anions.
