Why is alloying necessary?
Because it improves the material properties of the resulting metal.
The effect of temperature on magnetization?
Each material which can be magnetized has a material specific, so called Curie temperature. Above this specific temperature the material will lose its magnetism and the ability to be magnetized. Returning below this temperature, the material regains its magnetic properties.
Can material that look the same have different chemical properties?
Yes. Nitrogen and oxygen are both colorless, odorless gases. That means they share physical properties (their appearance, or lack thereof), but they have very different chemical properties because they are in different groups of the periodic table.
What are some examples of intensive properties?
Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density. Because intensive properties are sometimes characteristic of a particular material, they can be helpful as clues in identifying unknown substances.
What are some physical properties used by scientist to describe matter?
Some physical properties used to describe matter are density, weight, temperature size and color
Why is alloying necessary?
Because it improves the material properties of the resulting metal.
Why is the flow of material in the living environment described as cyclic?
The flow of material in the living environment is described as cycle because it is never ending. It is the same set of events that never end.
Why was Professor Robert Street famous?
because he developed the properties of magnetic material
Which is superior material SS410 or SS 431?
When compare to SS410,SS431 is the best material ,because of its physical properties. S.Dhandapani
What are the properties of material before and after burning?
after it is burned the colour will drain and it will become black because it has turned into ash.
How are properties useful in classifying material?
Constituents, appearance, shape, and taste are used to classifying materials. This is useful because materials with similar properties can be placed in the same category.
What is the definition of orthotropic material?
Orthotropic materials have different mechanical properties along each of its axes because its axes are mutually orthogonal twofold axes. Therefore, they don't have one set of properties, because their properties change depending on the direction of the axis used.
Are the properties of diamond commensurate with the nature of bonding?
Yes. Diamond is a hard material because it has strong chemical bonds.
Why are skis made out of plastic and metal?
Because the material properties are suitable, weight, springiness, slick surfaces, strength etc.
Why is Boron named Boron?
Boron was named Boron because of the properties it has. It comes from the Arabic word Buraq and the Persian word Burah, which are both words for the material "borax."
Why is the material neoprene used to make chest waders?
The reason is mainly because of how consistent efficient they are, known as the most rugged wader material and also because of they buoyant properties that make them double as personal flotation devices.
Why you use steel to prepare cycle spoke?
Because for most applications it's the best combo of strength/cost/material properties available.
