In other words, heat is transferred by conduction when adjacent atoms vibrate against one another or as electrons move from one atom to another. Conduction is the most significant means of heat transfer within a solid or between solid objects in thermal contact. Fluids—especially gases—are less conductive.

Conduction transfers heat by:
Conduction is the process of transferring heat from one particle of a body to another without actual motion. This process occurs in solids where particles are closely packed together.
Key points:
- In conduction, heat is transferred through direct contact between particles.
- As particles vibrate due to their thermal energy, they pass on this energy to neighboring particles through collisions.
- This transfer of energy continues until a thermal equilibrium is reached, where all particles have the same amount of thermal energy.
- Materials that are good conductors, such as metals, allow heat to transfer quickly due to their free electrons that can move and transfer energy efficiently.
- On the other hand, materials that are poor conductors, like wood or plastic, have particles that are not as free to move, resulting in slower heat transfer.
In conclusion, conduction is an essential process for transferring heat within solids and plays a crucial role in various everyday applications and thermal management systems.
