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:

In this section you are required to take derivatives - review Math Essentials (pages 21-27).

cont. Sec 3.1...

- note "inverse rule" --> eq. 3.1

- note "cyclic rule" --> eq. 3.2

- Definitions:

*Thermal expansion coefficient (α) = eq 3.5

*Isothermal compressibility (κ_T) = eq. 3.5

- Review of Table 3.1/3.22

- Derive useful form of V(T2) = V(T1)*(1+α*ΔT)

- Derive useful form of V(P2) = V(P1)*(1-κ_T*ΔT)
