Explain the phenomenon of transfer of heat by means of conduction.

Solution

i) Conduction is the phenomenon of the flow of heat through one part of the body to another from particle to particle in the direction of fall of temperature without any actual movement of the particles.
ii) According to kinetic theory, the molecules of the body are in continuous oscillatory motion. When one end of the conductor is heated, the atoms/ molecules at the hot end begin to vibrate faster and collide the slow neighbouring atoms.
iii) On colliding, the fast molecules transfer a part of their energy to slower molecules and put them in quick oscillations and thus show a rise in temperature.
iv) In this way, the heat travels from atom to atom until it reaches the other end of the conductor.
v) During the process of conduction, the atoms themselves do not move from one end to the other.
For example, all solids are heated through conduction.
