In which mode of transfer of heat the molecules do not actually move from one place to another? 1 .Conduction 2. Convection 3. Radiation 4. None of the above
Answers
Answer:
conduction
In conduction, heat is transferred from one place to another without the movement of molecules. However, in convection and radiation, heat energy is transferred through the movement of molecules.
Answer is 1 Conduction
Explanation:
In conduction, the molecule vibrant and hit each other to transfer the heat energy between them. The molecule need not to travel from one end to another. Therefore it is only possible in solid in which the the molecule didn't move but vibrant on heating.
In the convection method, molecule travel from the hot region to the college region. The case is the same when water is heated.
In Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often called infrared radiation. This is a type electromagnetic radiation .
The explanation was nice and not I am really sorry!
But next time I will try my best with my answers
Till then take care my friend
