Explanation:
Mechanism of heat transfer:
When one end of a piece of metal is heated, the heat is transferred to the other end by energized electrons moving to the other end.
Energized electrons:
- When the metal is heated, the electrons in the metal gain energy.
- The energized electrons move randomly within the metal due to thermal agitation caused by the increase in temperature.
Electron movement:
- The energized electrons move from the hot end towards the cold end of the metal.
- This movement of electrons carries the thermal energy with them, transferring it from the hot end to the cold end.
Conduction of heat:
- This process of energized electrons transferring heat from one end of the metal to the other is known as conduction.
- The electrons collide with other electrons and atoms in the metal, transferring their energy and causing the metal to heat up uniformly.
Therefore, the other end of the metal becomes hot due to the movement of energized electrons carrying thermal energy from the heated end to the colder end. This phenomenon explains why heating one end of a piece of metal results in the other end becoming hot.
