Question

Cooking utensils are made up of
A. Good conductors of heat
B. bad conductors of heat
C. neither good conduction nor bad conduction of heat
D. None of these

Answer 1

Hint: Conductor: A conductor is an object or type of materials that allows the flow of charge in one or more directions. Generally metals are a good conductor. Woods, plastic, clothes etc. are bad conductors. In metals the electrons move easily, so the heat transfer through one molecule to another is easy.

Complete step by step solution:
Cooking utensils are generally made up of metals like copper, aluminum, steel, brass etc. We know that metals are good conductors of heat and electricity. Heats are easily conducted through the base of the metals to the contents. But they are given with a handle of bad conductors to help save our hands. The charge density of the conductor is zero so they easily conduct.
Bad conductors or insulators are those who cannot conduct any type of heat and electricity. So they are used to make the handle of the cooking utensils to protect the hands from burning. Some commonly used handles are made of Bakelite.
So the answer is (A) Good conductors of heat.

Note: Mostly bad conductors are non-metal and they don’t conduct heat and electricity. But graphite is an exception. Copper is generally costly as compared to other metals so now-a-days pans made of stainless steel are in fashion. Electric charges are absent in the insulators. So we prefer metal to make the electrical equipment.
