Question

Which of the following statements is/are true with respect to conduction?
1. Conduction is a process in which particles move from the hot region to the cold region.
2. Conduction is a process in which paricles vibrate about their mean position to transfer energy.
3. Conduction does not require material medium for the transfer of energy.
4. Conduction is the prominent mode of heat transfer in solids.

• A. Only 1 and 3
• B. Only 2 and 4
• C. Only 4
• D. Only 1, 3 and 4

Answer 1

The correct option is B Only 2 and 4

During conduction, the particle near the heating end absorbs energy and starts vibrating. During vibration, it collides with the nearby particles resulting in transfer of energy.
Conduction requires material medium for transfer of heat and is prominent mode of heat transfer in solids.
