Fill in the blanks (10*1=10)
1.) Sedimentation is the process of allowing ____ to settle at the bottom of a mixture due to their higher density.
Answer: particles
2.) Decantation is the method of carefully pouring off the ____ from the settled sediment in a mixture.
Answer: liquid
3.) Filtration is used to separate ____ substances from a liquid by passing the mixture through a filter medium.
Answer: insoluble
4.) A common filter medium used in the process of filtration is a ____.
Answer: filter paper
5.) In the process of filtration, the liquid that passes through the filter paper is called the ____.
Answer: filtrate
6.) Filtration is an effective method for separating a heterogeneous mixture of ____ and a liquid.
Answer: solid particles
7.) A commonly used technique in the purification of water is ____.
Answer: filtration
8.) Water treatment plants often use ____ as a primary step to remove large impurities from the water.
Answer: sedimentation
9.) Sedimentation is particularly useful in separating mixtures where one component has ____ than the other.
Answer: higher density
10.) One advantage of filtration is that it can effectively remove ____ particles from a liquid.
Answer: solid
Short answer question (5*2=10)
1.) Explain filtration. What is residue?
Answer: Filtration is the process of separating solid substances from a liquid, by passing the mixture through filter paper. Residue is the solid left behind on the filter paper after filtration.
2.) Why should we boil water before drinking?
Answer: Boiling water kills microorganisms like bacteria and viruses that cause diseases. Boiling makes the tap water microbiologically safe to drink.
3.) Describe the process of decantation.
Answer: Decantation is the process of separating insoluble solid particles from a liquid or separating two immiscible liquids of different densities.
4.) Name two methods to make water safe for drinking.
Answer: Two methods to make water safe for drinking are filtration and boiling.
5.) Give two example of mixture that can be separated by sedimentation.
Answer: Two example of mixture that can be separated by sedimentation are sand and water, oil and water.
