Answer» Solution :Second law of thermodynamics cab be stated in a number of forms: 1. All spontaneous processes or naturally occurring processes are thermodynamially irreversible. 2. Without the help of an external AGENCY, a spotaneous PROCESS cannot to REVERSED. 3. The entropy of an ISOLATED system increase if it is to be spontaneous in a particular direction. 4. In a NON -isolated systemthe total entropy of both the system and surroundings must increase or must be positive. 5. The total entropy of the universe must tend to increase in a spontaneous process. `G=H-TS` |
