Term | Definition |
---|---|
entropy (S) | an extensive property in a closed system |
change in entropy | is the same for all the processes (both reversible and irreversible) between the two states, |
Specific entropy (s) | entropy per unit mass; an intensive property |
Mole specific entropy | units: kJ/kmol *K or Btu/lbmol * R |
isentropic process | → reversible & adiabatic |
entropy transfer | is positive if Q>0. s no entropy transfer associated with work |
Entropy production | is positive for irreversible process and zero for reversible process |
Statistical thermodynamics using microscopic viewpoint relates | entropy to the disorder of the system. |
