Thermodynamics

General Information and Review

• Print out and explain [1st Year's 3 Laws of Thermodynamics]
• [[AP - Major Concepts in Thermodynamics] (nothing in it right now, 9/30/15}
• [Zumdahl Notes on Internal Energy and Thermo Intro in Chapter 6] (Thermo Intro and Internal Energy notes)
• HW (in Zumdahl Pg230), #21, 23, and 25.
  • need to use 101.3J / (L-atm) when using w = -PΔV so that units will cancel.
  • you get that number/unit when you divide 8.314 J / (mole K) by 0.08206 L-atm / (mole K ).

Enthalpy Enthalpy

• [1st Year's Enthalpy Videos]
• [Zumdahl Notes for Enthalpy Intro in Chapter 6]
• Calculating Enthalpy change by:
  
  • Calorimetry Equations:
    • Non-phase change (system does not change phase): deltaH = (m)(deltaT)(c), where c = specific heat capacity (H₂O is 1.00cal/(g-degC) or 4.18 J/(g-degC) ). There are variation on this equation where the m and c are changed but the importance thing is that units cancel.
      • See [1st Year's Notes for Non-phase Change Heat Calculation Notes]
    • Phase change Equation: deltaH = (m or other) (Phase change Enthalpy change)
      • Big thing here is no deltaT (since in a phase change temperature does not change) and that the Phase change Enthalpy change term has some units as (m or other).
      • There are various names for Phase change Enthalpy change include Molar Heat of Vaporization, Heat of Condensation, etc.
