Question

What type of conductor should we use to make water pipes in cold countries?
A.Good conductor
B.Poor conductor or bad conductor
C.Material does not help in such cases
D.None of the above

Answer 1

Hint: Here we will go through the types of the conductors and then will decide which can be utilized to make the pipes of water in the cold countries. Different materials have different electrical properties and so their use depends on it.

Complete step-by-step answer:
Good conductors allow the transfer of heat and electricity where bad conductors do not allow the transfer of heat and electricity.
Here, in this case the pipes should be made from the poor conductors as they will not allow the heat to pass from water inside the pipe with the atmosphere outside to prevent it from freezing and to avoid pipes from busting.
Hence, from the given multiple choices the option B is the correct answer.
So, the correct answer is “Option B”.

Note: Do not get confused with the types of the conductors and also remember material also plays an important role in some cases. We also have semiconductors which are good conductors at certain temperatures and bad conductors at room temperature.
