Answer:
A. Decantation- Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. ... To put it in a simple way, decantation is separating immiscible materials by transferring the top layer to another container.
Example:For example, when a mixture of water and oil is present in a beaker, a distinct layer between the two consistency is formed, with the oil layer floating on top of the water layer.
B. Evaporation-
Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.
Example: Ironing Clothes. Have you ever noticed that ironing slightly damp clothes works best to get the wrinkles out? ...Glass of Water. ...Process of Sweating. ...Line Drying Clothes. ...Kettle Whistle. ...Drying of Wet Tables. ...Drying of a Mopped Floor. ...Melting a Glass of Ice.
C. Filtering- pass (a liquid, gas, light, or sound) through a device to remove unwanted material.
Example: Brewing coffee involves passing hot water through the ground coffee and a filter. The liquid coffee is the filtrate. Steeping tea is much the same, whether you use a tea bag (paper filter) or tea ball (usually, a metal filter). The kidneys are an example of a biological filter.
D. Sieving-
Sieving. Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. ... Sieves are also used to separate stones from sand.
Example:at home: draining the water from a pot of noodles.construction site: separating fine gravel from coarse gravel.laboratory: using filter paper to separate a liquid and precipitate.school: separating the chalk from the chalk dust.By cracking a nut finely and your can separate it.
Using Magnet:Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people's bodies.
Example:Compass. A compass uses a magnet to direct its needle to the north pole. ... Mag-Lev Trains. ... Vending Machines. ... Holding Things. ... Electric Motors.
