Match the following: Column A Column B A) A substance obtained by mixing two or more pure substances. 1. Sublimation B) A clear liquid obtained after filtration 2. Decantation C) A solid changing directly into vapour 3. Mixture D) A method for removing the husk from the grain 4. Winnowing E) Removing insoluble impurities from muddy water by allowing it to settle 5. Filtrate

A)-3 A mixture is a substance which contains two or more pure substances in it. We use different methods to separate the mixture like winnowing, hand-picking of stones from grains, etc. B)-5 The filtrate is the clear liquid obtained after filtration. Filtration is a method used to remove insoluble solute from solvents. C)-1 The sublimation is a process where a solid change directly into vapour due to rise in temperature. D)-4 The winnowing is the process where the wind is used to remove the husk from the grains. E)-2 The decantation is the process to remove insoluble impurities or solutes which do not dissolve in a solvent like water. We allow it to settle down as sediment before removing the water from mud.

Kiran observed his father separating husk and grains by winnowing method in the field and appreciated how wind flow helped in separation. On evaporation, salt is formed from seawater. Isn’t it? How would you appreciate this process?
