Flash Cards: Methods of Separation in Everyday Life

Handpicking is a method of separating components from a mixture based on differences in size, color, and shape, often done by hand.

Threshing is the process of separating grains from the stalks by beating them.

Sieving separates solid particles based on size using a sieve, allowing smaller particles to pass through while retaining larger ones.

Sedimentation is the process where heavier insoluble particles settle at the bottom of a liquid.

Decantation follows sedimentation, where the liquid is carefully poured off, leaving the solid behind.

Filtration is the process of separating solids from liquids by passing the mixture through a filter, retaining the solid and allowing the liquid to pass.

Magnetic separation is the process of removing magnetic substances from non-magnetic ones using a magnet.

Evaporation is the process of turning liquid into vapor, useful for separating solids dissolved in liquids.

Separating black pepper from rice in pulao is an example of handpicking.

A sieve is used to separate fine substances like flour from larger particles like bran.

The main purpose of winnowing is to separate edible grains from husk and other impurities using air.

Components of a mixture are the different substances contained within it, which can be separated by various methods.

A thresher is a machine that separates grains from their stalks and husk efficiently.

Salt can be purified from seawater by evaporating the water, leaving behind the solid salt.

Materials like cotton, charcoal, sand, and filter paper can be used for filtration based on particle size.

Decantation works by carefully pouring the liquid off from the settled solids without disturbing them.

Filtration of muddy water will retain mud particles on the filter while allowing clear water to pass through.

Churning separates butter from buttermilk by agitating curd so that butter floats to the top.
