Heat transfer by condition will not occur when____________?
Correct answer: D. temperatures of the two bodies are identical
- A. bodies are kept in vacuum
- B. bodies are immersed in water
- C. bodies are exposed to thermal radiations
- D. temperatures of the two bodies are identical
Explanation
Conduction is driven by a temperature gradient, so no net heat is conducted between bodies at identical temperatures. Vacuum prevents ordinary conduction between separated bodies, but conduction can still occur through a solid connection.
