How would you physically separate the following: Sand and waterSugar and waterOil and waterSand and gravelA mixture of lead and aluminum pellets
1) Sand and water: To separate sand and water you need to filter the mixtureThis will leave the sand as residue in the filter paper and the water will pass through the filter paper to the beaker2) Sugar and water: To separate sugar and water you will have to put the solution in a shallow dish and then let the water evaporate by heating itYou will be left behind with sugarIf you need the water, then when you are heating the solution you must collect the water vapor and condense it3) Oil and water: A mixture of oil and water is put into a separating funnel and then shaken and then left until it becomes stable againThe liquid with higher density, in this case water goes to the bottom of the separating funnel (because it is heavier than oil)When this is done, the bottom of the Separating funnel is opened and the water flows out, leaving only the oil left 4) Sand and gravel: Use a filter with sieve with holes about 2mm apart, the sand will fall through and the gravel will be trapped as it is more coarse 5) Lead and aluminium pellets: Fill a container with waterThe aluminum is light, and less dense than the water, so it will float to the top of the containerThe lead is heavy, and more dense than the water, so it will sink to the bottom of the containerYou can then separate the two easilyHope this helps.
