SA 234WPB is the code of a carbon steel; see the ASTM or ASME specifications.
Element
Breaking a mirror does not cause a change in the chemical properties of the mirror itself. The act of breaking the mirror may result in physical changes, such as the mirror's fragments having sharp edges, but the chemical composition of the mirror remains the same. Mirrors are typically made of a layer of reflective material, like silver or aluminum, which is deposited on the glass surface, and breaking the mirror does not alter this composition.
All the properties of metals are the result of their electron configuration, in which they have between one and three valance electrons and therefore tend to lose electrons when they engage in chemical reactions.
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 %
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.

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

is a change that you cant see
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
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
'Mechanical Properties' is a property which is the behaviour of the material when its linked to the application of force such as Strength.
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.
The process of breaking down the rock material without changing its chemical composition is called mechanical weathering.
A pure substance:cannot be separated into 2 or more substances by physical or mechanical meansis homogeneous, ie, has uniform composition throughout the whole sampleits properties are constant throughout the whole sampleits properties do not depend on how it is prepared or purifiedhas constant chemical composition
Each material has specific chemical properties.
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
