Insoluble - Water does not dissolve insoluble materials. In this sense, insoluble is a scientific term that refers to a material's property and how it reacts to environmental changes.
When a substance is insoluble, it does not change its state. Sand is a good example. When placed in water, the solid particles combine with the liquid particles to form a solution.
Insoluble materials, such as sugar, are not to be confused with soluble materials, which dissolve in water.
These characteristics, along with others such as hardness, flexibility, and transparency, determine which materials are used for specific purposes in daily life.
