On heating one end of a piece of a metal, the other end becomes hot because of

Options

  1. Aenergised electrons moving to the other end
  2. Bminor perturbation in the energy of atoms
  3. Cresistance of the metal
  4. Dmobility of atoms in the metal

Correct answer

A. energised electrons moving to the other end

Step-by-step solution

Conductivity of heat in metals is due to the presence of free electrons, which move due to increase in temperature.
