Which of the following describes how oil behaves in relation to water?

Oil exhibits a specific behavior when it comes to water due to its physical properties. Oil is less dense than water, which is why it floats on the surface when the two are combined. This phenomenon occurs because oil and water are immiscible, meaning they do not mix. When oil is introduced to water, it will form a distinct layer on top instead of merging or dissolving. Additionally, the structure of oil molecules allows them to form a lighter layer above water, further showcasing the differences in their density. Thus, oil's tendency to float is a fundamental characteristic that is critical for understanding the environmental impact of spills and the management of heating oil tanks.
