Question

In which mode of transfer of heat molecules pass on heat energy to neighbouring molecules without actually moving from their positions?
A. convection
B. radiation
C. conduction
D. none of these

Answer 1

The above problem can be resolved by using the concepts and fundamentals of heat transfer. The conduction is that method of heat transfer, in which the molecules do not show any motion within the specific point to cause the energy exchange. Instead, the actual method to transfer heat by means of conduction is by achieving the more and more vibration of the substance. These vibrations will bring the vibrations of the energy waves and thus creates an intensified progression of the energy waves from one specific point to another.

Complete step by step answer:
Consider two points, such that the heat transfer is to be carried out by a specific method. Then, the heat transfer that undergoes the thermal energy exchange within the molecule, without actually causing the particles' motion within the point, is known as the conduction heat transfer. Moreover, in this heat transfer mode, the heat from the substance gets transferred to another substance without causing the intermixing of the mass of the substance.
Therefore, the mode of transfer of heat molecules pass on heat energy to neighbouring molecules without actually moving from their positions is known as conduction

So, the correct answer is “Option C”.

Note:
Try to understand the concept behind every mode of heat transfer that occurs within the molecular interaction. There are three modes of heat transfer, namely conduction, convection, and radiation. Each mode of heat transfer has its significance and applications. Moreover, the conduction is that mode of heat transfer that occurs due to the vibration of the energy weaves, and convection is due to energy exchange between the liquid and other materials.
