9) Which of the following statements is NOT true? A) Thermosetting plastics are bad conductors of heat and electricity. B) Thermoplastics are good conductors of heat and electricity. C) Plastics do not get corroded easily. D) Plastic is also a polymer.
Answers
Answer:
A) Thermosetting plastics are bad conductors of heat and electricity.
B) Thermoplastics are good conductors of heat and electricity is not true
Definition of Thermoplastics:
- Thermoplastic is a sort of plastic. It turns into smooth on heating and once more hardens while cooled.
- Due to this belongings thermoplastics may be moulded into unique shapes.
- But like several plastic substances thermoplastics also are bad conductors of heat and electricity (Insulators) as they do now no longer permit heat and light to pass through them.
Explanation for incorrect option:
A) Thermosetting plastics are bad conductors of heat and electricity: Thermosetting plastics are used to make saucepan handles due to the fact they're bad conductors of heat and additionally on heating, those plastics do now no longer get softened.
C)Plastics do not get corroded easily: Plastics and ceramics in addition to composite substances are bad conductors and aren't vulnerable to electrochemical corrosion as metals.
D) Plastic is also a polymer: Plastics are a form of polymer composed of chains of polymers which may be in part natural or fully synthetic. Simply put, all plastics are polymers, however now no longer all polymers are plastics.
Thus,B) Thermoplastics are good conductors of heat and electricity is not true.
