Chemistry
Draw a well-labelled diagram to separate kerosene oil from water.
Answer
The mixture of kerosene oil and water is placed in a separating funnel, where they form two layers. Water, being heavier, forms the lower layer, and kerosene oil, being lighter, forms the upper layer. The stopper is opened to drain the water (the heavier liquid) into a vessel, and the process is stopped when the lower layer is completely removed, separating the two liquids.
