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.

• In the webpage for video, there is at the bottom an online Textbook section on this topic. You should review it but especially look at the Spontaneous related to volts (cell potential).
