Start Chapter 3
=Sec 3.1
- - Natural variables of U are T and V --> U(T,V), but first... P(V,T)
- - See equation 3.3 --> dP = ...
- How does P change with V (at constant T)? --> -nRT/V2
- How does P change with T (at constant V)? --> nR/V
- Final result --> dP = ...eq. 3.6, which has defined the terms:
- Thermal expansion coefficient (α) = eq 3.5
- Isothermal compressibility (κT) = eq. 3.5
In this section you are required to take derivatives - review Math Essentials (pages 21-27).
- - note "inverse rule" --> eq. 3.1
- - note "cyclic rule" --> eq. 3.2
