Solution
We will separate cooking oil and water by using a separating funnel as cooking oil and water are two immiscible liquids. Due to the difference in the densities of the two liquids, cooking oil, being lighter than water, floats over it and forms the upper layer, whereas water forms the lower layer. On opening the stop-cock, the lower layer of water comes out first and is collected in a beaker. Cooking oil is left behind in the separating funnel.
