Why is oil insoluble in water?

Oil is insoluble in water because it is non-polar while water is polar, causing oil molecules to separate and form a distinct layer.

How does sand behave in water?

Sand does not dissolve in water; instead, it settles at the bottom due to its solid particulate nature and density.

What are practical uses of substances insoluble in water?

Substances insoluble in water, like oil and sand, are important in processes such as water treatment to separate contaminants effectively.

What Are Two Substances That Are Insoluble in Water?
