Physical properties that can be expressed in numbers include mass, volume, length, temperature, density, pressure, and energy. These properties can be quantified using different units of measurement, such as kilograms, meters, degrees Celsius, etc.
Properties of minerals that can be expressed in numbers include hardness (using the Mohs scale), specific gravity, crystal structure, refractive index, cleavage, and color intensity (using spectrophotometry). These numerical values provide quantitative data that help in identifying and categorizing minerals accurately.
Some properties of minerals that can be expressed in numbers include hardness (using the Mohs scale), specific gravity (a ratio of the mineral's weight to the weight of an equal volume of water), and refractive index (a measure of how light bends as it passes through the mineral).
The physical properties of minerals are determined by their chemical composition and atomic structure.
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
The physical properties of compounds do not include chemical reactivity, which relates to how a substance undergoes chemical changes. Physical properties pertain only to characteristics such as color, melting point, boiling point, density, and solubility.
