    • Surface Tension
      Net pull of liquid molecules on the surface
    • Stronger intermolecular forces

      Greater the surface tension
    • Liquid has higher surface tension
    • Viscosity
      Measure of liquid's consistency or resistance to flow
    • Viscosity becomes high
      When flow becomes slow due to tight intermolecular forces
    • Vapor Pressure
      The pressure exerted by a vapor in a closed container
    • Vapor pressure
      Some molecules of a liquid escape into the gas phase on top of liquid which is called vapor
    • Volatile
      Liquids that are readily converted into gasses
    • Volatile liquids

      Have weaker intermolecular forces
    • Increased temperature
      Increased vapor pressure
    • Boiling Point
      The temperature where liquid starts to be converted into gas
    • Boiling Point
      Enough energy must be supplied to disrupt intermolecular forces
    • Molar Heat of Vaporization
      Energy needed to be supplied to convert liquid to without varying temperature
    • Crystalline Solids

      • Made up of highly ordered particles with a well-defined pattern
      • Sharp melting points
    • Crystalline Solids
      • NaCl, ruby, emerald
      1. ray Diffraction
      Process of diffraction or scattering x-rays on a crystal sample
    • Unit Cell
      • Well-ordered articles that represent the characteristics of the crystals
      • Conforms a certain crystal lattice
    • Amorphous Solids
      • Consists of different particles that lack a definite order
      • Melt within a temperature range and shatter into irregularly-shaped patterns
    • Amorphous Solids
      • glass, rubber, cotton candy
    • Spontaneous Reaction

      Occurs on its own without intervention of an external force
    • Spontaneous Reaction
      • Rust - Iron turns to rust when exposed to oxygen
    • Non-Spontaneous Reaction
      Occurs in the presence of an outside intervention
    • Non-Spontaneous Reaction

      • Converting rust into iron metal and oxygen gas
    • Entropy
      • A thermodynamics quantity of randomness or disorder of particles
      • Number of possible arrangements for a given quantity of particles
