properties

Properties are attributes or characteristics that describe a substance or material, helping us identify and differentiate it. These include physical traits like color, shape, size, texture, melting point, and density, which can be observed or measured without changing the substance. Some properties, called chemical properties, describe how a substance reacts with other materials, such as its flammability or reactivity. Properties are essential for selecting materials for specific purposes, understanding how they behave, and predicting their responses in various conditions. Understanding properties allows us to classify, compare, and work effectively with different substances and materials.
