Is heat a transfer of energy

WebWhen the thermometer is warmed, the liquid expands by more than the volume of the hollow space in which it is confined, and so some of it must move from the bulb into the capillary tube. It should be conduction and then convection/advection, not radiation. Radiation is usually the slowest heat transfer. WebHeat transfer is thermal energy in transit due to a temperature difference. A topic you may have touched on in Chemistry is thermodynamics. Thermodynamics deals with equilibrium processes and endpoints. It doesn’t give us rates. Heat transfer deals with temperature gradients and non-equilibrium phenomena. Note
