What is the difference between a wet sieve and a dry sieve

A wet sieve analysis involves using water to wash finer particles through the sieve, while a dry sieve analysis does not involve any added moisture and relies on natural particle movement through the sieve openings. Wet sieve analysis is typically used for cohesive materials, while dry sieve analysis is more commonly used for non-cohesive materials.
The laboratory apparatus for sieve analysis typically include sieves, a sieve shaker, a balance, and a pan to collect the material passing through the sieves. Additionally, a brush and cleaning tools may be needed to maintain the equipment and ensure accurate results.
Sieve analysis is commonly used in civil engineering to determine the particle size distribution of soil samples, which is important for designing structures such as roads and foundations. It is also used in agriculture to assess the size distribution of seeds or grains for planting purposes. Additionally, sieve analysis can be used in the pharmaceutical industry to ensure the uniformity and quality of powdered medications.
Sift dry ingredients through a fine sieve to remove any lumps or impurities, creating a lighter and fluffier texture in your baking or cooking. This process also helps aerate the ingredients, resulting in a more even distribution and better incorporation of ingredients in your final dish.

Dry erase markers are typically considered to be non-polar because they contain ingredients like alcohol and glycol that are water-soluble and do not have a significant difference in electronegativity between the atoms in the molecules.
