### Expansion and Compression of a Gas

Calculation of Work and Heat in Various Processes. Work Done by a Gas When a gas expands, it does work on its environment. Consider a cylinder filled with gas. For a small displacement dx, the work done by the gas is dW by = F dx= pAdx= p (Adx)= p dV This is just the area under the p-V curve: Examples: The amount of work performed while going from one state to another is not unique!, CHAPTER 13. THERMODYNAMICS (MOSTLY CHAPTER 19) 189 It is clear that areas under path on the pV diagram depend on the path and thus the work done by a system is not the same. Similarly the heat transferred to a system Q depends on the path it takes and thus dQ (or per-haps ОґQ) is not an exact diп¬Ђerential. Processes corresponding to isothermal.

Note that least work is done when the compression is isothermal, and in the case of an air compressor for instance, isothermal compression is desirable in order to reduce the power input necessary from its engine or motor. An approximation to isothermal compression is achieved by multi-stage compression with intercooling. Now we know from logarithm properties is the same thing as nRT times the natural log of V2 over V1. So there you have it, we actually calculated the real value.
