Question

Which of the following is true with respect to conduction?

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

Answer 1

The correct option is B Atoms vibrate about their mean positions to transfer energy.

Atoms in any substance vibrate. On applying heat, the atoms near the hot end absorbs energy and the intensity of vibration increases. These atoms collide with the nearby atom and transfer energy to the nearby atoms.
This type of heat transfer is called conduction.
