Class 6 Separation of Substances

Name the process shown here.

• Sedimentation

• Decantation

• Dissolution

• Sieving

The process used to separate grains from stalks

• Threshing

• Winnowing

• Hand-picking

• Sieving

The method of separation in which heavier and lighter components of a mixture are separated with the help of wind is called

• Threshing

• Winnowing

• Sedimentation

• Sieving

To separate a mixture of stones and wheat flour, the method used is

• Sieving

• Winnowing

• Evaporation

• Filtration

The process by which gas changes into liquid is

• Cooling

• Condensation

• Freezing

• Steaming

The process by which we can separate salt and water from their mixture is

• Filtration

• Evaporation

• Sedimentation

• Decantation

Sand, salt and water mixture is provided to you. The sequence of processes used to separate them would be

• Decantation/filtration, Evaporation, Condensation

• Evaporation, Condensation, Decantation/filtration

• Decantation/filtration, Condensation, Evaporation

• Evaporation,Decantation /Filtration, Condensation

The filtration process is used at our home to separate

• Paneer and liquid residue of sour milk

• Tea and tea leaves

• Fruit juice and fruit pulp

• Wheat flour and husk

A solution in which no more solute can be added is called

• Saturated solution

• Unsaturated solution

• True Solution

• Mixture

The solubility of a solution can be increased by

• Adding more water to it

• By freezing the solution

• By heating the solution

• By adding alum to it
