Chapter 5 The Second Law of Thermodynamics - CPP
www.cpp.eduThe Second Law of Thermodynamics 5.1 Statements of The Second Law Consider a power cycle shown in Figure 5.1-1a that has the following characteristics. The power cycle absorbs 1000 kJ of heat from a high temperature heat source and performs 1200 kJ of work. Applying the first law to this system we obtain, DE cycle = Q cycle + W
ENTROPY AND THE SECOND LAW OF THERMODYNAMICS
www.smallscalechemistry.colostate.eduSecond Law of Thermodynamics and can be stated as follows: For combined system and surroundings, en-tropy never decreases. Actually, it always increases. This is really what makes things happen. The fi rst law of thermodynamics, that energy is conserved, just ells us what can happen; it is the second law that makes things go.
