THERMODYNAMICS

CHAPTER INTRODUCTIONIn previous chapter we have studied thermal properties ofmatter. In this chapter we shall study laws that governthermal energy. We shall study the processes where work isconverted into heat and vice versa. In winter, when we rubour palms together, we feel warmer; here work done in rubbingproduces the heat . Conversely, in a steam engine, the heat of the steam is used to do useful work in moving the pistons,which in turn rotate the wheels of the physics, we need to define the notions of heat,temperature, work, etc. more carefully. Historically, it took along time to arrive at the proper concept of heat.

12.11 Second law of thermodynamics 12.12 Reversible and irreversible processes 12.1 3 Carnot engine Summary Points to ponder Exercises 304 PHYSICS Thermodynamics is the branch of physics that deals with the concepts of heat and temperature and the inter -conversion of heat and other for ms

ENTROPY AND THE SECOND LAW OF THERMODYNAMICS

www.smallscalechemistry.colostate.edu

Second 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.

The Second Law of Thermodynamics For the free expansion, we have ΔS > 0. It is an irreversible process in a closed system. For the reversible isothermal process, for the gas ΔS > 0 for expansion and ΔS < 0 for compression. However, the gas itself is not a closed system. It is only a closed system if we include both the gas and the reservoir.

The First Law of Thermodynamics The first law of thermodynamics is an expression of the conservation of energy principle. Energy can cross the boundaries of a closed system in the form of heat or work. Energy transfer across a system boundary due solely to the temperature difference between a system and its surroundings is called heat.
