A drop of oil is placed on the surface of water. Which of the followin...
Explanation:
When a drop of oil is placed on the surface of water, the following things happen:
Spread of Oil:
The oil drop will start spreading as soon as it comes in contact with the water surface. This is because the oil molecules have a lower surface tension than water molecules. Therefore, the oil spreads over the water surface in an attempt to minimize its surface area.
Formation of a Thin Layer:
As the oil spreads over the water surface, it forms a thin layer. The thickness of this layer depends on the volume of the oil drop and the surface area of the water. This layer will be very thin, and it will cover a large area.
Formation of a Distorted Drop:
If the volume of the oil drop is large compared to the surface area of the water, it will not spread completely. In this case, the oil drop will float as a distorted drop on the water surface.
Conclusion:
Therefore, option B is correct. When a drop of oil is placed on the surface of water, it will spread as a thin layer over the water surface.
