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 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 are photo conductive polymers?
photoconductive polymers are materials that change their electrical conductivity when subject to light (infra red- visible - ultraviolet - gamma). They are mainly used in photocopiers and holography.
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.
How do properties of matter determine use?
The properties of matter, such as density, conductivity, reactivity, and hardness, dictate how materials can be utilized in various applications. For instance, metals with high conductivity are ideal for electrical wiring, while materials with low reactivity, like glass, are preferred in chemical containers. Additionally, the hardness of a material influences its use in construction or tools. Ultimately, understanding these properties enables the selection of the right material for specific purposes.
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.
What influences radiational cooling?
Properties of the material such as thermal conductivity, specific heat, and emissivity, and the temperature of the surroundings.
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 the electrical conductivity of bleach?
Bleach, primarily composed of sodium hypochlorite dissolved in water, has moderate electrical conductivity due to the presence of dissolved ions. The conductivity can vary depending on the concentration of bleach; more concentrated solutions generally exhibit higher conductivity. Typically, the conductivity of household bleach solutions ranges from 1 to 10 mS/cm, depending on the specific formulation and dilution.
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
