What is the best method to separate a mixture of solid particles of the same material into lost of different size?
By using a series of sieves with increasingly small mesh openings, you can separate the material (soil, for instance, or a mixture of rocks, gravel, pebbles, and sand) into different size ranges. Sieves come in all kinds of mesh sizes, from large (with low mesh numbers, such as 2, which has an opening of 11.2 mm) to very fine (with high mesh numbers, such as 635, which has an opening of 0.02 mm).
There are many commercially available mesh sizes, so you don't typically use them all to separate the material. Instead, you might choose a few selected ones that depends on the material you are separating. One common way to do this is to stack the sieves (they are made to interlock when stacked) from lowest mesh number (biggest opening) on top to highest mesh number (smallest opening) on the bottom, and put them on a sieve shaker. As the shaker vibrates, the material gradually works its way downwards by gravity, and each particle ideally goes as far down as it can until it meets a screen that is too small for it to pass through. Obviously, if the particles are wet or sticky, this technique doesn't work very well.
The different lots that have now been created are often referred to by their mesh ranges, such as -2/+10 mesh, meaning the sample has passed through the #2 mesh sieve and has been collected on the #10 mesh sieve. The "negative" sign in this case means "smaller than"; there is no "-2" mesh size.
A common mesh size you will see on bottles of chemicals in powder form is -325 mesh, which means the particles are smaller than 44 microns (.044 mm).

Which type of mixture has an uneven distribution of particles?
A heterogeneous mixture has an uneven distribution of particles. In this type of mixture, the different substances are not uniformly mixed, making it easy to distinguish and separate the components. Examples include salad, cereal with milk, and a mixture of sand and gravel.
Method to esparate different size particles?
One method to separate different size particles is by using sieving, which involves passing a mixture of particles through a sieve with different mesh sizes. Smaller particles can pass through finer mesh sizes while larger particles are retained. This allows for the separation of particles based on their size.
What method could you use to separate 2 things that have different densities?
One method that could be used to separate two things with different densities is centrifugation. By spinning the mixture at high speeds, the components will separate based on their density, with the denser material moving towards the outside and the lighter material towards the center. This allows for easy separation of the two components.
What is the sorting of smaller material from larger material using mesh or sieve?
The process of sorting smaller material from larger material using mesh or sieve is called screening. This technique involves passing a mixture of materials through a screen with specific-sized openings, allowing smaller particles to pass through while larger particles are retained. Screening is commonly used in industries such as mining, agriculture, and construction to separate materials based on size.
If two different particles have same speed in a medium chormatography is possible or not write reason?
Chromatography is not possible with two different particles that have the same speed in a medium because chromatography relies on the differential interactions between a sample mixture and the stationary phase in the column, which results in separation based on their different affinities. If the particles have the same speed, they would not separate from each other, making chromatography ineffective for separating them.
Which tool can be used to quickly separate a dry mixture containing particles of different sizes?
A sieve or a sieve shaker can be used to quickly separate a dry mixture containing particles of different sizes. The mixture is poured onto the sieve, which allows smaller particles to fall through while larger particles are retained on top.
When the particles in a mixture are not the same size?
When the particles in a mixture are not the same size, they can separate based on their different sizes through methods such as filtration or sedimentation. This property allows for the physical separation of the components of the mixture.
What are 3 ways to separate solid solutes from liquid solvents?
Filtration: using a filter paper or porous material to separate solid particles from a liquid by passing the mixture through. Evaporation: allowing the liquid to evaporate, leaving behind the solid solute. Centrifugation: spinning the mixture at high speeds to separate the solid particles from the liquid based on their different densities.
When particles separate and spread evenly throughout a mixture it is called?
When particles separate and spread evenly throughout a mixture, it is called diffusion.
How do you separate colloid mixture?
One method to separate a colloid mixture is through centrifugation, where the mixture is spun at high speeds to separate the components based on their different densities. Another method is filtration, where the mixture is passed through a filter to separate the larger colloidal particles from the smaller ones or the liquid. Additionally, dialysis can be used to separate colloids based on size by allowing smaller particles to pass through a semi-permeable membrane while retaining larger particles.
What is used to separate magnetic material from a mixture of other substances?
A magnet. The magnet will attract the magnetic material to it and so separate the magnetic material from the mixture.
A sieve can be used to separate a mixture of different what?
You can separate the juice and pulp of tomatoes from the seeds and skin when making homemade tomato juice.
What is the mixture in which particles of a material are more or less evenly dispersed throughout a liquid or gas?
A homogeneous mixture, also known as a solution, is when particles of a material are evenly dispersed in a liquid or gas. This means that the components are uniformly mixed at the molecular level and do not separate upon standing.
What is frequently used to separate particles from a mixture?
A sieve.
How do you separate heterogeneous mixtures using filtration?
Filtration is a method used to separate a heterogeneous mixture by passing it through a porous material, like filter paper or a sieve. The solid particles in the mixture are trapped by the filter, while the liquid or smaller particles pass through. This results in the separation of the solid component from the liquid component of the mixture.
What force will separate a Mixture of iron and sand?
A mixture of iron and sand can be separated using a magnet. Iron is a magnetic material, so when a magnet is brought close to the mixture, the iron particles will be attracted to the magnet and can be removed from the sand. This method takes advantage of the different physical properties of the two materials.
What is a mixture in which particles eventually separate and settle out is a what?
Suspension.
