Modeling How do I explain it? Synthesis How do I make it? Three central goals Why do substances undergo phase transitions with changing temperature or pressure? How do we MODEL these systems to Explain/Predict their behavior? Modeling Macroscopic Microscopic or Particulate Symbolic NaCl Three different perspectives UA GenChem Macro vs Micro Macroscopic Description We measure properties: Temperature ( T ) Pressure ( P ) Volume ( V ) Microscopic Description We model systems as composed by particles: Number ( N ) Mass ( m ) Speed ( v ) Kinetic Energy ( KE ) Potential Energy ( PE ) The challenge: Use microscopic descriptions to explain macroscopic behavior UA GenChem Solid Liquid Gas 1 mL of Water = 33444444444444444444444 molecules A Particulate Model of Matter Basic Assumptions : Particles could represent anything we want: atoms, molecules, ions....
