Webb22 maj 2024 · In thermal conduction, energy is transferred as heat either due to the migration of free electrons or lattice vibrational waves ( phonons ). There is no movement of mass in the direction of energy flow. Heat transfer by conduction is dependent upon the driving “force” of temperature difference. Webb12 sep. 2024 · Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred …
