The plasties that are poor conductors of heat and electricity
Answers
Answer:
plastics and all non metals are poor conductor
Answer:
Plastic is a poor conductor of heat because it has no delocalised electrons which aid in thermal transfer. It is thus an insulator. The number of delocalised electrons in a substance determines its ability to transfer heat.
Explanation:
Hint: The conductivity is the major fact used to choose the material for making cooking pans handles. Plastics are usually a bad conductor of heat and electricity which means that it cannot conduct electricity or heat when passed through it.
Complete answer:
-Conductors are defined as those compounds which can conduct heat and electricity. The conductors are divided into good conductors of heat and bad conductors of heat based on their conductivity.
-Good conductors are those which can conduct heat and electricity. Example of a good conductor of heat is iron.
-A bad conductor is those which cannot conduct heat and electricity. Example of a bad conductor of heat is wood plastics.
-If cooking pans are made up of iron handles or other good conductors of heat. It will be difficult to hold the cooking pan as it will transfer the heat to the handle and holding the pan like this can burn the skin of your hands.
-If cooking pans are made up of plastic handles which are bad conductors of heat therefore they cannot transfer the heat from the cooking pan into the handles and the cooking pan can be easily held without causing any harm to skin.
-Hence, cooking pans are usually made up of plastics as they are a bad conductor of heat.
-Thus, the statement Cooking pans have plastic handles is true
