• A. lower density than water
• B. higher density than water
• C. density equal to a water
• D. none of these

Answer 1

The correct option is A lower density than water

In separating funnel, the oil forms an upper layer and water forms lower layer because the oil has a lower density than water. The lower layer of water then can be removed from funnel by opening the tap of the funnel.
In this way, the mixture of oil and water can be separated.
