classify the metals and non metals on the basis of their conductivity
Answers
Explanation:
Classification
Substances can be classified into two categories i.e. between metals and non-metals on the basis of some of their properties.
Metals:
There are many substances which are known as metals because some of their unique properties, such as iron, copper, gold, silver, sodium, aluminium, etc.
Physical properties of Metals:
Metallic Lusture:
Metals have shining surface. This property of metals is called metallic lusture. Because of this property (metallic lusture) gold, silver, platinum, etc. are used to make jewelry.
Hardness:
Metals are generally hard. But hardness varies from metals to metals. But, sodium is an exception which is very soft. Sodium metal can be cut using a knife.
Because of hardness iron metal is used in making of garter of bridges, rail lines, rail compartment, car body, etc.
Malleability:
Metals are malleable. Metals can be beaten into thin sheet. This character of metals is called malleability. Because of this character iron metal is used to make thin sheets which are used in making of car body, containers, etc.
Gold and silver are most malleable metals that’s why these metals are used in making jewelries.
Ductility:
Metals are ductile. Metals can be drawn into thin wires. This character of metals is called ductility. Because of this character of ductility, iron is used in making of wires which are tied up to make strong ropes. Ropes made of iron are used in cranes, bridges, etc.
Gold is the most ductile metal. Gold is such ductile that about 2km of wire can be drawn from one gram of gold.
Good conductor of Heat:
Metals are good conductor of heat. Because of this property cooking utensils are made of metals, such as aluminium, copper, iron, etc.
Good conductor of electricity:
Metals are good conductor of electricity. Because of this property copper and aluminium metals are used to make electric wires.
Sonorous:
Metals produce ringing sound when beaten. Because of this property metals are used to make bells in schools, temples and churches. This property of metals to produce ringing sound is called sonorous.
Answer:
metals and non metals can be classified into conductors and insulators on the basis of their conductivity. Conductors are those materials that allow electricity and heat to pass through them with ease ,while , insulators are those materials that do not allow electricity and heat to pass through them. please mark it as brainlist if it is useful.
