  1. needle is a bad conductor of heat

  2. needle is a good conductor of heat

  3. needle is an insulator

  4. none of the above

Show answer
Correct Option: B
Explanation:

If needle is burnt then the heat transfer through the whole length of needle is faster, because needle (metal), being a good conductor of heat, heat passes along the whole length by conduction, in which heat is transferred by one atom to another connected atom quickly.
