The second law of thermodynamics states that heat flows spontaneously from an object at a higher temperature to an object at a lower temperature, and that it is impossible for heat to flow spontaneously from a colder to a hotter object. Therefore, if the cooler block were to cool further while the warmer block simultaneously warms further, this would violate the second law of thermodynamics.
