Why anisotropic properties are direction dependent?
Anisotropic properties are direction dependent because the material exhibits different physical properties (such as conductivity, elasticity, or optical properties) along different crystallographic axes. This is due to the asymmetry in the arrangement of atoms or molecules within the material, leading to varying responses to stimuli along different directions.
Why must the property of a material be considered before it is used to make a product?
Understanding the properties of a material is crucial because it determines how the material will behave in different conditions, such as strength, flexibility, durability, and conductivity. Selecting the right material with the desired properties ensures that the product will be suitable for its intended use and will perform as expected. Failure to consider properties could result in the product not functioning correctly or lacking in performance.
Is rubber attracted to magnet?
no
Is Li magnetic?
No, Li (lithium) is not magnetic because it does not have unpaired electrons in its electron configuration, which are necessary for a material to exhibit 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.
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.
What is the bulk modulus of viscous material?
Viscous materials do not have a bulk modulus in the traditional sense because they do not deform elastically under pressure like solids. Instead, their behavior is more accurately described by viscosity and shear properties.
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
Why consider the property of a material when choosing its use?
Considering the properties of a material is important because it determines how the material will perform in a given application. Different properties like strength, flexibility, conductivity, and durability can impact the material's suitability for specific uses. Choosing the right material based on its properties can result in optimal performance and longevity of the final product.
Why are the physical properties physical properties?
Physical properties are characteristics of a material that can be observed or measured without changing the composition of the material. These properties give information about how a material behaves under different conditions (e.g. melting point, density, conductivity). They are considered "physical" because they are related to the material's physical state and structure, rather than its chemical properties.
Why does light travel slower in high density materials?
Light travels slower in high density materials because the speed of light is determined by the properties of the material it is passing through. In denser materials, the light interacts more frequently with the atoms and molecules, leading to a slower overall speed. This phenomenon is described by the refractive index of the material.
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 many sets of properties do you need to observe in order to classify a material as a heterogeneous mixture?
You need to observe at least two sets of properties to classify a material as a heterogeneous mixture. This is because a heterogeneous mixture is a combination of different substances that can be distinguished by their properties, such as size, color, and phase. By observing multiple sets of properties, you can confirm that the mixture is not uniform in composition.
Why anisotropic properties are direction dependent?
Anisotropic properties are direction dependent because the material exhibits different physical properties (such as conductivity, elasticity, or optical properties) along different crystallographic axes. This is due to the asymmetry in the arrangement of atoms or molecules within the material, leading to varying responses to stimuli along different directions.
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.
