WitrynaHeat transfer will only take place between 2 bodies when they have a substantial temperature difference. Now, after some time you come back to find that the tea in the cup has cooled down to say 50°C and you have a sip of the same. This is the second law of heat transfer. Heat will only flow from a body at higher temperature to a body at a ... WitrynaEquation 23.1 is known as Fourier's law. * The minus sign accounts for the fact that heat flows from a higher temperature to a lower temperature. Thus, for example, in Figure 23.1, heat flows in the positive x-direction.For this to happen the temperature must decrease as x increases. Thus, ΔT is negative in Figure 23.1.The units of k are W/m · … WitrynaFourier’s law states that the negative gradient of temperature and the time rate of heat transfer is proportional to the area at right angles of that gradient through which the heat flows.
