What else can I help you with?
Are all the particles of sediment the same size?
No, sediment particles can vary in size from fine clay and silt to coarser sand and gravel. Sediment can contain a mixture of different particle sizes depending on the source and transport processes.
What is frequently used to separate particles from a mechanical mixture?
A sieve or strainer is frequently used to separate particles from a mechanical mixture based on differences in particle size. This allows smaller particles to pass through while larger particles are retained, creating a separation based on particle size.
What mixture has the smallest particles?
A colloid is a mixture with particles smaller than those in suspensions and emulsions. Colloids have particles that are between 1 to 1,000 nanometers in size, making them the smallest among the three types of mixtures.
What is a heterogeneous mixture that can only be seen indirectly and does not settle upon standing?
A colloid is a heterogeneous mixture where the particles are intermediate in size between a solution and a suspension, making them visible only with the aid of a microscope. Due to the small size of the particles, they do not settle out upon standing, resulting in a stable mixture.
What is one difference between a colloid and solution?
One difference is the size of particles: in a solution, particles are uniformly dispersed at a molecular level, whereas in a colloid, particles are larger and dispersed throughout the mixture but do not settle out.
Are all the particles of sediment the same size?
No, sediment particles can vary in size from fine clay and silt to coarser sand and gravel. Sediment can contain a mixture of different particle sizes depending on the source and transport processes.
What kind of mixture has medium size particles settles out on standing and scatters light?
A colloid is a type of mixture in which medium-sized particles do not settle out on standing and scatter light. However, a suspension is a type of mixture with medium-sized particles that do settle out on standing and can scatter light.
Is sugar a heterogeneous mixture or is it a homogeneous mixture?
Sugar is a compound, a pure substance, as it only contains sucrose.
Can a homogeneous mixture scatter light?
Yes, a homogeneous mixture can scatter light if the size of the particles in the mixture is similar to the wavelength of light. This phenomenon is known as the Tyndall effect, where the light is scattered as it passes through the mixture due to interactions with the particles.
What has a liquid mixture in which particles settle out?
A suspension is a liquid mixture in which particles settle out over time. The particles are usually larger in size and do not dissolve completely in the liquid. Examples include sand in water or chalk in water.
What is frequently used to separate particles from a mechanical mixture?
A sieve or strainer is frequently used to separate particles from a mechanical mixture based on differences in particle size. This allows smaller particles to pass through while larger particles are retained, creating a separation based on particle size.

What allows you to separate the particles in a mixture?
A physical property such as size, shape, or density can be used to separate particles in a mixture. Common methods include filtration, distillation, chromatography, and centrifugation.
Sediments with a mixture of sizes are known as?
The sediments with a mixture of sizes are known as poorly sorted sediments. This means that the particles have not been sorted by size and can range from fine to coarse within the same sediment deposit.
What basic lab technique involves the separation of a mixture's components through differences in particle size?
Filtration is the basic lab technique that involves separating a mixture's components based on differences in particle size. By passing the mixture through a filter, larger particles in the mixture are retained while smaller particles and fluids pass through.
