Where does the heat energy dissipated by friction come from?

WebThe heat dissipation of a heated metal box is dominated by the thermal resistance of the metal/air interface, not by the thermal conductivity of the box itself. Characterizing the thermal resistance of that interface will be difficult without taking a lot more measurements. WebHeat conduction, also called diffusion, occurs within a body or between two bodies in contact. It is the direct kinetic energy exchange of particles through the boundary between two systems. Heat transfer by the method of conduction to attain thermal equilibrium when an object is at a different temperature from its surroundings or any other body. dr. kondash scranton
