Describe physical properties of liquids such as evaporation, vapor pressure, boiling point, viscosity and surface tension.
Apply the concept of hydrogen bonding to explain the properties of water (specifically high surface tension, high specific heat, low vapor pressure, high heat of vaporization, and high boiling point).
