(SVNA7) Ch. 2, pp. 37 - 55 Assignments Handouts (on web unless stated otherwise) HW #1 due Wed, Aug 31 Outline 1. Complete lecture 3. 2. Duhems theorem. 3. Phase rule and Duhems theorem for reacting systems. 4. Engineering importance of phase rule and Duhems theorem. 5. Equilibrium. 6. Reversibility. 7. Energy equivalence (how nature works). 8. First law of thermodynamics (how nature works) and implications. Key Concepts 1. U internal energy (thermodynamic property or coordinate): implicitly defined by 1 st Law H enthalpy (thermodynamic property or coordinate): mathematically defined, in part, for engineering convenience, H = U + PV (2.11) 2. Differential and integrated form of enthalpy: ( ) dH dU d PV = + (2.14) ( ) H U P V = + (2.15) 3. It was observed long ago that if you heat a solid object in an oven, the temperature of the...
