Flows from hotter object to cooler object
WebHeat can only flow from hot to cold to obey the second law of thermodynamics. The change of entropy of a system is. dQ/T. in which dQ is the heat exchanged (+ for gain, - for loss) … WebAnswer (1 of 4): The direction of heat transfer between objects is always from the object with a higher temperature to the object with a lower temperature. This is based on the Second Law of Thermodynamics, which states that heat naturally flows from hotter objects to cooler objects in order to r...
Flows from hotter object to cooler object
Did you know?
WebConduction—the flow of heat from a hotter object to a cooler object or from a hotter region to a cooler region of the same object—is the most common mechanism of heat transfer. The formula governing this is H=ΔQΔt=kA (TH−TCL)H=ΔQΔt=kA (TH−TCL), where HHH is known as the heat current. This formula applies to ________________.
