Solid - All minerals will be solids at normal temperatures on Earth. Naturally occurring - Minerals occur in nature. Solids that are made in a chemistry lab don't count as minerals. Inorganic - Minerals don't come from plants, animals, or other living organisms. Fixed chemical structure - Specific minerals will always have the same chemical ... Physical Properties Of Some Important Minerals Physical properties such as color, crystal form, hardness, cleavage, luster, etc. are useful in identifying minerals and they provide clues to the internal structures or chemical compositions of unknown grains.

Chemistry is the science of matter, its properties, and changes. In your classroom work in chemistry, you will learn a great deal of the information that has been gathered by scientists about matter. But, chemistry is not just information. It is also a process for finding out more about matter and its changes.
Jun 13, 2019 · Properties in science is defined as :” The properties of matter include any traits that can be measured, such as an object's density, colour, mass, volume, length, malleability, melting point, hardness, odour, temperature, and more.”

Optical properties Optical properties provide the basis for many rapid, indirect methods of analysis such as proximate analysis by infrared absorbency or light scattering. Optical properties also determine the appearance of milk and milk products. Light scattering by fat globules and casein micelles causes milk to appear turbid and opaque. Calcite is a rock-forming mineral with a chemical formula of CaCO 3. It is extremely common and found throughout the world in sedimentary, metamorphic, and igneous rocks. Some geologists consider it to be a "ubiquitous mineral" - one that is found everywhere. Calcite is the principal constituent of limestone and marble. These rocks are ...
