Question

Cooking pans have plastic handles.
A. True
B. False

Answer 1

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.
Therefore, the correct option is A.

Note:
The thermal conductivity is the ability of the substance to conduct heat or electricity. The thermal conductivity is denoted by symbol K.
