What is the classification of electrical materials?
Materials in electronics can be classified as electrotechnical, constructional and special. Electrotechnical materials are classified by four groups: Conductors Semiconductors Isolators Magnetic materials.
How can you classify the properties of materials?
A. Materials can be described and classified according to the following physical properties: size, shape, mass, texture, color, and material composition. Students can observe materials’ physical properties by using tools that include rulers, balances, thermometers and hand lenses.
What are the three main properties of materials?
The four properties of material are mass, toughness, hardness and malleability. EXPLANATION: Materials occurs in nature according to their compactness. Material are categorized into three common states in which they are present, they are solid liquid and gas.
What are the properties of materials answer?
The four properties of material are mass, toughness, hardness and malleability. Explanation: Materials occurs in nature according to their compactness. Material are categorized into three common states in which they are present, they are solid liquid and gas.
What are the two properties of air?
The properties of air are: Air takes up space. Air has mass. Air is affected by heat. Air exerts pressure. Air can be compressed. Air is affected by altitude. Related questions.
What are 10 raw materials?
Examples of raw materials include steel, oil, corn, grain, gasoline, lumber, forest resources, plastic, natural gas, coal, and minerals.
How many different materials are there?
In general, materials that widely used in this universe are divided into 4 types, which are Metal, Polymers, Ceramic and Composite. There are plenty of manufacturing processes that have been developed to form a product.
What type of material is glass?
Glass is a solid-like and transparent material that is used in numerous applications in our daily lives. Glass is made from natural and abundant raw materials (sand, soda ash and limestone) that are melted at very high temperature to form a new material: glass.
Which metal is broken easily?
Answer: sodium and potassium are soft metal they can be cut by using knife where as zinc is non ductile and non maleable in nature..
What are tough materials?
In order to be tough, a material must be both strong and ductile. For example, brittle materials (like ceramics) that are strong but with limited ductility are not tough; conversely, very ductile materials with low strengths are also not tough.
What are hard materials?
Those materials which cannot be easily compressed, cut, bent or scratched are called hard materials. Examples: Iron, glass. Those materials which can be easily compressed, cut, bent or scratched are called soft materials.

What are the examples of physical and chemical properties?
The general properties of matter such as color, density, hardness, are examples of physical properties. Properties that describe how a substance changes into a completely different substance are called chemical properties. Flammability and corrosion/oxidation resistance are examples of chemical properties.

What are the electrical properties of semiconductors?
At absolute zero, semiconductors are perfect insulators, The density of electrons in conduction band at room temperature is not as high as in metals, thus cannot conduct current as good as metal. The electrical conductivity of semiconductor is not as high as metal but also not as poor as electrical insulator.
