List differences between gases, liquids, and solids. Discuss the Physical conversion of states of matter. Only occurs when Hydrogen is bonded to Fluorine, Oxygen, or Nitrogen. Define and discuss the property of surface tension as it applies to cohesive and adhesive forces.
Surface tension is the energy required to expand the surface area of a liquid by a unit amount.
Heat of Fusion- Energy required to convert a quantity of solid to the liquid state at the melting point temperature. The energy required to convert a quantity of Liquid to the gaseous state at the boiling point temperature. Heat of Sublimation- Energy required to convert a solid to the vapor state directly at the Sublimation temperature. Define Critical Temperature and critical pressure of a liquid. Define Vapor Pressure.
