Bakelite is an early plastic which was made from synthetic components and was used in the telephone casings, radio, electrical insulators, jewelry, kitchenware and more for its heat resistant and electrical non-conductivity properties. It is a poor conductor of electricity.
Which one is poor conductor of heat and electricity?
Lead is a poor conductor of heat because it readily reacts with the atmosphere to form lead oxide, where we know metal oxides are poor conductors of heat and electricity as well. Hence, the correct option is (A), Lead.
Can Bakelite conduct heat?
Bakelite is a special material that is used for its ability to resist heat. Unlike metal, which is an excellent conductor of heat, Bakelite does not conduct heat well, which makes it the perfect material for creating pressure cooker handles.
Is Bakelite an insulator of heat?
Bakelite is an insulator because it has very high resistance. It is a thermosetting polymer and has high strength.
What are poor heat conductors?
Metals and stone are considered good conductors since they can speedily transfer heat, whereas materials like wood, paper, air, and cloth are poor conductors of heat. These conductive properties are rated based on a “coefficient” which is measured relative to silver.
Is Bakelite conductive?
Bakelite has a low electrical conductivity and high resistance to heat and chemicals. … Bakelite is most commonly used for making electrical switches due to its high resistance to heat and low conductivity. Earlier it was used for making machine parts of electrical systems too.
Is Bakelite heat resistant?
Bakelite has a number of important properties. It can be molded very quickly, decreasing production time. Moldings are smooth, retain their shape and are resistant to heat, scratches, and destructive solvents. It is also resistant to electricity, and prized for its low conductivity.
Does electricity flow through Bakelite?
Bakelite is an insulator it is very bad conductor and it has very high internal resistance that resist the circuit current flow through it..
Why is Bakelite a good insulator?
Bakelite is an electrical insulator……. … If BaKeLiTe is dry then it works like an insulator but if it is wet and it comes in the contact with the high voltage current then it can conduct electricity…..
Is Bakelite example of insulator?
Explanation: Bakelite is an insulator it is very bad conductor and it has very high internal resistance that resist the circuit current flow through it.. … Bakelite is a a good insulator, and a poor conductor of heat.
Why Bakelite is used in making electrical switches?
Bakelite is a thermosetting plastic. It is a poor conductor of heat and electricity. Hence, it is used for making electrical switches and plugs.
What are three poor heat conductors?
Bad conductors of heat i.e. insulators:
What is another name for a poor conductor?
Poor conductors of heat are also called insulators.
What do you mean by poor conductor of heat give example?
Example – Copper, Iron. Bad conductors – “The substances through which heat is not conducted easily are called bad conductors of heat or poor conductors of heat”. Example – Wood, Cloth.
