Question

Which of the following is/are true with respect to conduction?

• A. Atoms move from hot region to cold region
• B. Atoms vibrate to transfer energy
• C. Atoms are not required
• D. Heat energy gets transferred instantaneously

Answer 1

The correct option is B

Atoms vibrate to transfer energy

During conduction, the particle near the heating end absorbs energy and starts vibrating. During vibration, it collides with the nearby atom and transfers energy to nearby atoms. In this manner with time, energy gets transferred from one end to another. As we can see atoms are involved, therefore conduction can’t happen in absence of atoms.
