उत्तर
The second law of thermodynamics deals with transfer of Energy.
Explanation:
The second law of thermodynamics deals with two statements related to Kelvin-plank and Clausius.
Kelvin-plank statement says that any such device cannot be made, which exchanges heat from a single energy source and converts all that energy to an equal amount of work. Clausius's statement ensures that it is impossible to transfer heat from a cold reservoir to a hot reservoir without any external work. So in both statements, the transfer of energy and its direction of transfer was of some importance.
