CBSE Notes – Key Points

These notes are useful for quick revision before examinations. Read the important definitions, keywords, tables, and facts carefully to strengthen your conceptual understanding.

Important Keywords

The following keywords are frequently used in this chapter and should be remembered carefully.

KeywordMeaning
MixtureA physical combination of two or more substances.
HandpickingRemoving visible impurities by hand.
ThreshingSeparating grains from harvested stalks.
WinnowingSeparating lighter particles from heavier particles using wind.
SievingSeparating particles based on their size.
SedimentationSettling of heavier insoluble particles at the bottom.
DecantationCarefully pouring the clear liquid into another container.
FiltrationSeparating insoluble solids from liquids using a filter.
EvaporationObtaining dissolved solids by removing the liquid.
ChurningSeparating butter or cream from curd.
Magnetic SeparationSeparating magnetic substances using a magnet.

Important Definitions

Learn the following definitions carefully as they are frequently asked in examinations.

TermDefinition
MixtureA physical combination of two or more substances that can be separated by physical methods.
FiltrationThe process of separating insoluble solids from liquids using a filter.
SedimentationThe settling down of heavier insoluble particles in a liquid.
DecantationThe process of pouring the clear liquid without disturbing the settled particles.
EvaporationThe process of converting a liquid into vapour to obtain dissolved solids.

Methods of Separation

Different mixtures require different methods of separation depending on the physical properties of their components.

MethodUsed ForExample
HandpickingRemoving large visible impuritiesStones from rice
ThreshingSeparating grains from stalksHarvested wheat
WinnowingSeparating lighter and heavier particlesHusk from grain
SievingSeparating particles of different sizesFlour and bran
SedimentationSettling heavy particlesMuddy water
DecantationSeparating clear liquidOil and water
FiltrationRemoving insoluble solidsTea leaves from tea
EvaporationObtaining dissolved solidsSalt from seawater
ChurningSeparating butterButter from curd
Magnetic SeparationSeparating magnetic materialsIron filings from sand

Selection of Separation Method

The suitable method of separation depends upon the physical properties of the substances.

PropertySuitable Method
Difference in SizeHandpicking, Sieving
Difference in WeightWinnowing
Difference in DensitySedimentation, Decantation
Difference in SolubilityFiltration, Evaporation
Magnetic PropertyMagnetic Separation

Applications in Daily Life

Methods of separation are used in many daily-life activities.

  • Removing iron pieces from scrap.
  • Separating grains after harvesting.

Important Facts

Remember these important facts for examinations.

  • A mixture contains two or more substances.
  • No single method can separate every mixture.
  • Physical properties determine the method of separation.
  • Handpicking is suitable only when impurities are few and visible.
  • Winnowing requires moving air.
  • Sieving separates particles of different sizes.
  • Filtration removes insoluble solids from liquids.
  • Evaporation is used to obtain dissolved solids.
  • Churning separates butter from curd.
  • Magnets attract magnetic substances such as iron.
