Why are some materials used for specific purposes in preference to others?
Materials are chosen for specific purposes based on their physical, chemical, and mechanical properties. Factors such as strength, durability, cost, availability, and compatibility with the desired application play a key role in selecting the most suitable material. Additionally, considerations around weight, corrosion resistance, thermal conductivity, and electrical properties contribute to the decision-making process.
What is 50a470 material?
50A470 is a type of electrical steel used in transformer cores. It has specific magnetic properties that make it suitable for converting electrical energy efficiently in transformers. The "50" indicates the alloy composition, while "A470" denotes its specific characteristics and properties.
What is the difference between specific conductance and conductivity?
me too searching!!
What are the observable characteristics or properties of common solution found at home and stores?
Common solutions found at home and stores typically have clear or colorless appearance, a specific odor, and may have a specific taste or pH level. They can be found in liquid, powder, or solid form, and may exhibit properties such as conductivity, solubility, and density. Additionally, they can have specific uses or applications based on their composition and properties.
What are the intensive and extensive properties of copper?
If you want actual values, you'll need to be more specific, I'm not about to list hundreds if not thousands of properties in the hopes that one of them is the one you want.It's probably more useful to discuss what the two terms mean. "Intrinsic" properties are those that are characteristic of the material itself ... it doesn't matter (within reason) how much of the material there is. Intrinsic properties are things like melting point, boiling point, color (sometimes), heat capacity, atomic/molecular mass, and so on. "Extrinsic" properties are those that depend on the "extent" of the material ... that is, how much there is of it. Mass, weight, and volume are extrinsic properties (though in some cases, dividing one extrinsic property by another can give you an intrinsic property again ... mass divided by volume yields density, an intrinsic property).
What specific property of metals accounts for their unusual conductivity?
Outermost orbital shell of a metal has very few electrons with corresponding values of energy. This specific property accounts for the unusual electrical conductivity of metals. Highest conductivity occurs in metals with only one valence electron.
How is to test electrical properties of polymers?
Most scientists just use either a resistance meter (also called an ohmmeter because the units it measures in are ohms) or a conductivity meter. A conductivity meter measures the ability of something to flow current, not the ability of it to resist current flow. You use one when you're dealing with extremely high resistances--in the hundreds, or thousands, of megohms. The unit for conductivity is the Mho--"ohm" spelled backwards.
Kinds of physical property?
Density, hardness, melting point, boiling point, thermal conductivity, electrical conductivity, mechanical properties, magnetic properties, refraction index and other optical properties, specific heat capacity, etc.
Will coins conduct or insulate electrical energy?
Coins made of metal, such as copper or silver, can generally conduct electrical energy due to their high conductivity properties. However, if the coins are coated with a non-conductive material, they may insulate electrical energy. It ultimately depends on the specific material and construction of the coins.
What influences radiational cooling?
Properties of the material such as thermal conductivity, specific heat, and emissivity, and the temperature of the surroundings.
What physical properties are size indepentent?
There are very many. Some are:Density (and specific gravity), electrical conductivity, thermal conductivity, boiling point, latent heat of vaporisation, melting point, latent heat of melting, elasticity, malleability, ductility, electronegativity (though that could be considered a chemical property), temperature.
Are ferro magnetic materials insulators?
Not necessarily. Ferromagnetic materials can be conductors, semiconductors, or insulators depending on their specific composition and structure. Magnetic properties and electrical conductivity are independent characteristics of a material.
What is conduct electricity means?
The ability of a material to conduct an electric current is termed as ELECTRICAL CONDUCTIVITY. Generally, ELECTRICAL CONDUCTIVITY is the ratio between ELECTRICAL FIELD STRENGTH and the CURRENT DENSITY of the conductor. The unit is Sm-1. It is also known as SPECIFIC CONDUCTANCE. ELECTRICAL CONDUCIVITY = (ELECTRICAL RESISTIVITY)-1 The unit of ELECTRICAL CONDUCIVITY is ohm- meter.
What are the roles of the 5 properties of water?
Water has very many properties: mass, density, colour, odour, refractive index, specific heat, electric conductivity, thermal conductivity, and so on. There is nothing in the question which clarifies which 5 properties you are interested in. Consequently, the question cannot be answered.
What is the effect of density on conductivity?
*Electrical conductivity or specific conductivity [sigma] is a measure of a material's ability to conduct an electric current. When an electrical potential difference is placed across a conductor, its movable charges flow, giving rise to an electric current. The conductivity σ is defined as the ratio of the current density J to the electric field strength E : J=Sigma.E
Describe other properties of metals you could not test?
Some properties of metals that may be difficult to test include their resistance to corrosion, their ability to conduct heat and electricity, as well as their ductility and malleability. These properties are often evaluated through specific tests, such as exposure to certain environments for measuring corrosion resistance, or conducting electrical and thermal conductivity tests.
Specific conductivity of water in power plants?
Specific conductivity is a measure of the ability of water to conduct an electrical current. It is highly dependent on the amount of dissolved solids (such as salt) in the water. Pure water, such as distilled water, will have a very low specific conductance, and sea water will have a high specific conductance.
