- Did you know that you can separate mixture with sand, gravel alcohol dissolve salt and water?Sounds impossible right? But it is possible! Sand and gravel can be separated by pouring the mixture into a sieve with holes small enough to trap the gravel but large enough to let the sand through. Sand and water can be separated using a filter—the water will pass through the filter but the sand will not.
- While the metals in a scrap yard can be separated by sorting Sand and gravel can be separated by pouring the mixture into a sieve with holes small enough to trap the gravel but large enough to let the sand through.
- A filter is similar to a sieve in that both are used to separate mixtures by trapping larger substances in holes that allow smaller substance to pass through. However, a filter has much smaller holes than a sieve, so that it is used to separate tiny, insoluble solids from liquids or gases. Sieves can separate larger solids from smaller solids or liquids.It is very difficult to separate oil and water once they are mixed because they are both liquids. As a result, many kinds of separation techniques are not very effective.
- But a mixture of different oil components that evaporate at different temperatures could be separated through the process of distillation.
- That would be all! Thank you for reading! By the way, I am Andrea T. Azarcon from 12 STEM Veritas. BYE!
