Heat transfer by conduction results due to the transfer of free electrons, kinetic energy & vibrational energy from one molecule to another. Conduction heat transfer cannot take place____________________?
Correct answer: B. Between two bodies not in physical contact with each other
- A. Between two bodies in physical contact with each other
- B. Between two bodies not in physical contact with each other
- C. From one part of a body to the another part of the same body
- D. Both B & C
Explanation
Conduction requires molecular or electronic interaction across a material interface, so two bodies must be in physical contact. Conduction can also occur within different parts of the same continuous body, making option C incorrect.
