WebThe second law of thermodynamics has various formulations. There is the "Clausius formulation," which can be stated in a very intuitive way: "No process is possible whose sole result is the transfer of heat from a cooler to a hotter body." There is also the "Kelvin-Plank principle," which states that "no cyclic process exists whose sole result is the absorption … WebHeat added to a system at a lower temperature causes greater randomness than in comparison to when heat is added to it at a higher temperature.
