Question

Select conductor of heat from the following:
A. Paper
B. Aluminum
C. Plastic
D. Rubber

Answer 1

Hint:Material that directs heat and warmth electricity are known as good conductors. Others are known as bad conductors. This kind of question requires a brief explanation of the conductors. It also needs explaining all the following options provided will help us to choose between the good and the bad conductors.


 Complete step by step solution:
The conductor has the following properties as given below:
Conductors are materials that permit electrons to flow freely from particle to particle.
In a conductor, electric current will flow freely, whereas in insulators it will not.
Metals such as copper characterize conductors, while most non-metallic solids are said to be good insulators.
Some liquids are good electrical conductors. Mercury is an excellent example.
At enormously low temperatures, some metals will conduct electricity better than any known substance at room temperature. This phenomenon is called superconductivity.
The answer is OPTION (ii) Aluminium is a conductor of heat. Aluminum is an exceptional heat and electricity conductor and, regarding its weight, is nearly twice as good a conductor as copper. In the metals, we can see that the valence electrons are already detached because of the metallic bonds between atoms.

Note:The state of the atoms influences the rate of the energy transfer. Low energy atoms as solids transfer the best. High energy atoms as gases are the worst transfers of energy. Liquids in between. The actual heat flow rate is limited by the worst component in the contract. This can be due to the highly energetic state of either atom or their contact zone or their electron density.
