A) The second law of thermodynamics is not a consequence of the first law; it is an independent principle stating that the total entropy of an isolated system can never decrease over time. B) Heat flows spontaneously from a hot body to a cold one, not the reverse, regardless of the process's reversibility. C) It is possible to convert work entirely into heat through processes like friction. D) It is possible to transfer heat from a cooler to a hotter body using external work, as in a refrigerator. Therefore, all given statements are false.
