FAQs on Worksheet Solutions: Methods of Separation in Everyday Life - Science Class 6

1. What are some common methods of separation used in everyday life?
Ans. Some common methods of separation used in everyday life include filtration, evaporation, distillation, and magnetism.
2. How does filtration work as a method of separation?
Ans. Filtration works by passing a mixture through a filter that allows the liquid component to pass through while retaining the solid components.
3. When is evaporation used as a method of separation?
Ans. Evaporation is commonly used to separate a soluble solid from a liquid by heating the mixture until the liquid evaporates, leaving behind the solid.
4. Explain how distillation is used in everyday life for separation.
Ans. Distillation is used in everyday life to separate mixtures of liquids with different boiling points by heating the mixture and collecting the vapors that condense back into liquid form.
5. How can a magnet be used as a method of separation in everyday life?
Ans. A magnet can be used to separate magnetic materials from a mixture by attracting the materials to the magnet and pulling them away from the non-magnetic components.
