Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
pure substances
Hydrogen.
chemical property is any of a material's properties that becomes evident during a chemical reaction
the nature of the material weathered (shape, size, composition) the nature of the weathering agent the frequency of the weathering agent the properties of the surrounding environment
The term "parent material" is generic and it refers to any type of substance or material which undergoes some process to produce another material. The term "parent material" can be used in geology, chemistry or radioactivity for three of many examples. In Earth science and geology , it may refer to mineral composition that weathers easily can produce more soil, for example. In nuclear physics, it is the radioactive material that decays to produce daughter nuclei. In chemistry, it is material that undergoes chemical change to yield another chemical.
the main difference is of SPELLINGS!. material science is knowing the basic knowledge about materials i.e their properties. and material engineering is that, by knowing the properties of a particular material you design or engineer that material for desired applications.

Atom
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.
the chemical properties of timber tell us about the chemical composition of tree material and physical properties tell us about the apperence and color of the timber
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.
a substance
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.
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.
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
No. A pure substances has a definite and constant composition.
SA 234WPB is the code of a carbon steel; see the ASTM or ASME specifications.
Each material has specific chemical properties.
