Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.

Taste is derived from the chemical composition and chemical properties of a material.


Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.

It would depend on your definition of a chemical. A chemical is: "a substance produced by or used in a chemical process." And, water is a chemical because it is be used in chemical reactions such as neutralization, redox, etc. I believe what you're asking though is if water is a chemical substance: "a material with a definite chemical composition." Water is also a chemical composition because of its electron configuration in its valence shell which defines its chemical properties.


Chemical substances (also sometimes referred to as a pure substances) are often defined as any material with a definite chemical composition in most introductory general chemistry textbooks. According to this definition a chemical substance can either be a pure chemical element or a pure chemical compound. However, there are exceptions to this definition, a pure substance can also be defined as a form of that has both definite composition and distinct properties and the chemical substance index published by CAS also includes several alloys of uncertain composition.

No, it is a pure substance. A "pure substance" does not mean an element. Rather, it means that the given substance has definite physical and chemical properties. "Pure substances" can be either "Elements" or "Compounds" because all substances belonging to these categories have definite physical and chemical properties.A mixture does not have definite physical and chemical properties, and combine in varying proportions.


No. Boiling water is a physical not a chemical change, and yet clearly steam has very different properties than liquid water does. A chemical change is one which will change the composition or identity of the material. So not only will its properties change, but it's chemical composition will also be changed




Each material has specific chemical properties.


These chemical properties are different for each solid material.


SA 234WPB is the code of a carbon steel; see the ASTM or ASME specifications.


Physical change is the change that happens only to the physical properties of a material, without causing any change to its chemical composition.

Every metal, which are elements, has chemical and physical properties. Chemical properties can only be observed when the composition of the substance changes. An example is wood burning, the wood is no longer the same material. Also note that these changes are called chemical changes. Physical properties can be observed only when the composition does not change. An example is the color, or the taste of a substance. In addition physical changes are observed only if the composition has not changed. An example is tearing a piece of paper, the paper still has the same composition but has gone through a physical change. A common misconception between chemical and physical changes is that a physical change can be reversed while a chemical change cannot not be reversed which is absolutely false.


CRS is the acronym for Corrsion Resistant Steel; for the chemical composition of a typical material see the link below.

Breaking glass is a physical change, as it does not change the chemical composition of the material.

The chemical composition of the steel 1.0120 is:- manganese: 1,6 %- silicon: 0,5 %- chromium: 0,3 %- nickel: 0,3 %- carbon: 0,12-0,17 %


For all materials physical properties are related to some characteristics as density, hardness, refractive index etc. and the chemical properties are related to some characteristics as chemical reactivity, flammability, oxydation etc. Physical properties are characterized by getting back the original material by changing its form, state, etc. Chemical properties are characterized by a complete change in the material itself i.e. you cannot get back the same material.
