rheological properties

Rheological properties describe how materials deform and flow when subjected to forces. They tell us if a substance behaves more like a solid, resisting shape changes, or like a liquid, flowing easily. For example, honey flows slowly and resists stretching, indicating high viscosity, while water flows quickly, showing low viscosity. These properties are important in industries like food, cosmetics, and materials engineering, helping to predict how substances behave during processing, application, or use—whether they spread easily, hold their shape, or react differently under various conditions.
