using water for separating
When a liquid is separated from a solid, it is considered a mixture. A solution is a homogeneous mixture where the components are evenly distributed at a molecular level. In the case of a liquid-solid separation, the two components are physically distinct and can be separated by methods like filtration or decantation.
The residue of a mixture typically consists of the solid components that remain after a separation process, such as filtration or evaporation. It includes undissolved particles, precipitates, or any solid material that did not pass through a filter or evaporate with a solvent. The specific composition of the residue depends on the original mixture and the separation method used.
Probably "filtration" is the answer sought, although this is certainly not the only possibility.
To separate camphor from a mixture of sand and camphor, you can use sublimation. Heat the mixture gently so that the camphor sublimes (changes from solid to gas) and then reverts back to solid form on a cool surface. The sand will remain behind as a residue, allowing the separation of camphor from the mixture.
The different melting points of the metals would allow separation by heating the mixture to a temperature where one metal melts while the other remains solid, enabling them to be physically separated.

Centrifugation is a separation technique that relies on the components of a mixture settling into layers based on their densities. By spinning the mixture at high speeds, the heavier components move to the bottom, while the lighter components stay at the top, allowing for easy separation.
A solid mixture in the classroom could be a combination of different solid substances like a mixture of sand and salt or a mixture of iron filings and sulfur. Students could explore these mixtures to learn about separation techniques such as filtration or magnetism.

Filtration is the separation technique used to separate water from an insoluble solid. The mixture is passed through a filter paper or sieve, which traps the solid particles while allowing the water to pass through.
A Spinolator is a type of centrifuge machine that separates solid particles from a liquid mixture. When the mixture is spun at high speeds, the heavier particles are pushed to the outer edges of the container while the liquid remains in the center, allowing for the separation of the two components. This process is commonly used in industries such as food processing and wastewater treatment.
Mechanical separation is any process that will separate compounds or elements that are found in a mixture. This commonly entails removal of particles of solid or liquid drops from a gas or a liquid.

Two examples of solid mixtures in a classroom are wax on the floor and paint on the wall.
Decantation is commonly used to separate a mixture of a liquid and a solid component, where the solid settles at the bottom. Examples include separating sand from water, separating tea leaves from brewed tea, or separating settling chalk from water.
