Conduction of heat transfer - Definition, Examples ...

2020-12-1  Conduction Of heat transfer is the transfer of internal energy by microscopic collisions of the particles and the movement of free electrons within a body. Colliding particles, which contain molecules, atoms, and electrons, transfer kinetic energy and P.E, together called internal energy.

Conduction Heat Transfer - an overview

Conduction heat transfer is the transfer of heat through matter (i.e., solids, liquids, or gases) without bulk motion of the matter. In another ward, conduction is the transfer of energy from the more energetic to less energetic particles of a substance due to interaction between the particles.
