- - - - w = -PΔV
- - - - Liquids to Gas
    - - Solids to Liquid
    - - Substance to Oxygen
    - - Substance formed
- - - - Work – the energy used to move an object over some distance
    - - Heat flows from warmer objects to cooler objects.
    - - KE = ½mv2
      - Electric
      - Light (Electromagnetic)
      - Motion (Large scale)
      - Thermal (Microscale)
      - Sound
    - - Potential energy arises when a force operates on an object
      - Force – any kind of push or pull exerted on an object
      - Electrostatic
      - Gravitational
      - Magnetic
      - Chemica
      - Elastic
      - PE = mgh
    - - SI unit of energy is the joule (J)
        
        1J = kg * m2 / s2
      - Calorie (cal)
        
        1 cal = 4.184 J
- - - - H = E + PV
      - ΔH = q
      - So, at constant pressure, the change in enthalpy is the heat gained or lost.
      - A process is endothermic when ΔH is positive (heat is absorbed).
      - A process is exothermic when ΔH is negative (heat is released).
