Astrophysics - the arena where all cosmic events unfold
In science, properties refer to the characteristics that can be used to describe and identify a material or substance. These characteristics can be observed, measured, or tested. Properties help differentiate one material from another and can be either physical or chemical. Physical properties are characteristics that can be observed or measured without changing the substance's chemical composition. Examples include: Color : The visible hue of the substance. Texture : The surface quality of the substance (e.g., rough, smooth). Shape : The three-dimensional form of the substance. Density : The mass per unit volume. Hardness : The resistance to scratching or indentation. Melting point : The temperature at which a substance changes from solid to liquid. Boiling point : The temperature at which a substance changes from liquid to gas. Chemical properties describe how a substance interacts with other substances or changes during a chemical reaction. Examples include: Reactiv...
