Question

Mother mixed oil and water in kitchen by mistake. Suresh told her that he can separate the mixture. Name the technique used by Suresh and explain how he will do. Draw the diagram and write the principle of this technique.​

Answer 1

Suresh can use a separation funnel to separate the mixture of oil and water based on their difference in density.

Step-by-step explanation:

Separation of Oil and Water

Suresh can separate the mixture of oil and water by using a technique called separation funnel. This technique takes advantage of the fact that oil and water are immiscible, meaning they do not mix together. Suresh will pour the mixture into the separation funnel and shake it to allow the two liquids to come into contact. The oil, being less dense, will float on top of the water. Suresh can then open the stopcock at the bottom of the funnel and allow the oil to separate from the water and collect it in a separate container.

The principle behind this technique is based on the difference in density between oil and water. Oil is less dense than water, so it floats on the top. The separation funnel allows the two liquids to separate into layers based on their density, and the more dense liquid (water) can be drained off from the bottom, leaving the less dense liquid (oil) behind.

By using the separation funnel, Suresh can effectively separate the mixture of oil and water.
