Identify the physical mechanism of heat conduction in a soli

Identify the physical mechanism of heat conduction in a solid.

A) Due to the collisions of the molecules during their random motion

B) Due to the vibrations of the molecules in a lattice

C) Due to the absorption of radiations

D) Due to the energy transport by free electrons

Solution

it is due options A,B,D

Explaination:

Energy may be transferred by means of electrons which are free to move through the lattice structure. In addition to this energy may be transferred by means of vibration in the lattice structure
