[QUOTE="TeethWhitener, post: 6868982, member: 511972"] Taking this a step further, we can see that heat flow from high temperature to low temperature is simply a reflection of the second law of thermodynamics. When an object at high temperature comes into contact with an object at low temperature, the energy flows in the direction in accordance with the second law ##\Delta S\geq0##. Since a change in energy is associated with a much larger change in entropy for low temperature objects than for high temperature objects, the increase in energy will have to happen to the low temperature object in order to be consistent with ##\Delta S\geq0##, so heat will flow from hot to cold.
