True or false?

(a) A mixture of milk and water can be separated by filtration.
(b) A mixture of powdered salt and sugar can be separated by the process of winnowing.
(c) Separation of sugar from tea can be done with filtration.
(d) Grain and husk can be separated with the process of decantation.


Answer :

(a) A mixture of milk and water can be separated by filtration.\(\rightarrow \) FALSE

REASON: No, filtration is used for the separation of solid components of the mixture from the liquid. But here both the components are liquids.


(b) A mixture of powdered salt and sugar can be separated by the process of winnowing. \(\rightarrow \) FALSE

REASON: No, winnowing is used to separate heavier particles from the lighter particles which can be blown away by the wind. But here both sand and sugar are heavy particles.


(c) Separation of sugar from tea can be done with filtration. \(\rightarrow \) FALSE

Reason: No, separation of sugar from tea can not be done with filtration because sugar is soluble in water.


(d) Grain and husk can be separated with the process of decantation. \(\rightarrow \) FALSE

REASON: No, decantation is used to separate insoluble solid components from the liquid component.
