Lesson 5 - Coggle Diagram

- - - - As the heat is giving out from a system, the temperature of the system will decrease
      - As the heat energy of the system decreases, ∆H is in negative value
    - - As the heat is taking in from surrounding, the temperature of the system will increase
      - As the heat energy of the system increases, ∆H is in positive value
- - - - The degree of disorder, the highest entropy to lowest entropy is
        gas,
        aqueous,
        liquid then
        solid
        
        For example,
        2Na(s) + 2H20(l) -> 2NaOH(aq) + H2(g)
        2 mole of solid and 2 mole of liquid to 2 mole of aqueous and 1 mole of gas
        hence, the ∆S is positive
      - the number of mole of the molecules
        
        For example,
        2SO3(g) -> O2(g) + 2SO2(g)
        2 mole of gas to 3 mole of gas
        hence, the ∆S is positive
