5 Unique Properties of Water

Due to polarity water exhibits:

  1. Cohesion (sticks to self)
  2. Adhesion (sticks to other things)
  3. High specific heat capacity / high vaporization
  4. Universal solvent
  5. Less dense as a solid

Unique Properties of Water & How Polarity is Involved

  1. Cohesion --> H-bonds
  2. Adhesion --> H-bonds / dipole attractions
  3. High specific heat capacity / high vaporization --> H-bonds
  4. Universal solvent --> Polarity
  5. Less dense as a solid --> H-bonds & bent shape

Which property?

  1. Water comes off of the tap in a stream --> Cohesion
  2. Humans sweat to cool their core body temperature --> High heat capacity
  3. Water boils at 100℃ & methane (CH4) at -161℃ --> High heat vaporization
  4. Water "climbs" up pant legs on a rainy day --> Adhesion
  5. Lakes freeze from the top to the bottom --> Less dense as solid
  6. Sugar is a solute in Coke & Pepsi --> Universal solvent
