Prompt: The beaker contains a unique solution, showcasing a fascinating interplay of substances. At the top of the beaker, a layer of oil floats, and within this oil, elemental benzene molecules are suspended. Simultaneously, at the bottom of the beaker, water resides, hosting another elemental benzene along with a floating polymer. The intriguing aspect arises from the interaction between the benzene molecules in the oil and water phases. An extraordinary event unfolds as a membrane forms at the interface between the oil and water layers. This membrane is a result of the benzene molecules' self-organization, creating a barrier that separates the two liquid phases. Due to the formation of this benzene-derived membrane, a distinct boundary is established, preventing the polymer from crossing between the oil and water layers. The polymer, unable to traverse this membrane, remains confined to the water phase. This phenomenon highlights the unique properties and interactions of benzene molecules in this particular solution, demonstrating their ability to create a selective barrier that influences the movement of other substances within the beaker.
