Topics in States of Matter

1

Three States of Matter and Intermolecular Forces

  • Three states exist due to balance between intermolecular forces and thermal energy
  • Solids: Strong intermolecular forces, fixed shape and volume, particles vibrate in fixed positions
  • Liquids: Moderate intermolecular forces, definite volume but take container shape, particles can move within boundaries
2

Gas Laws and Ideal Gas Equation

  • Boyle's Law: P ∝ 1/V at constant T,n → PV = constant
  • Charles' Law: V ∝ T at constant P,n → V/T = constant
  • Gay-Lussac's Law: P ∝ T at constant V,n → P/T = constant
3

Kinetic Molecular Theory and Real Gases

  • KMT assumptions: Point particles, no intermolecular forces, elastic collisions, random motion
  • Average kinetic energy ∝ absolute temperature
  • Pressure results from molecular collisions with container walls
4

Liquefaction and Critical Constants

  • Critical temperature (Tc): highest temperature at which gas can be liquefied by pressure alone
  • Critical pressure (Pc): minimum pressure needed to liquefy gas at critical temperature
  • Critical volume (Vc): molar volume at critical temperature and pressure
