Water

• What are the 5 key properties of water?

  • It is a metabolite
  • It is a solvent
  • High specific heat capacity
  • High latent heat of vaporisation
  • Strong cohesion
• How is water a metabolite?

  • Used in condensation and hydrolysis reactions
• How is water a solvent?

  • Because of its polarity it can dissolved many substances
• Why is having a high latent heat of vaporisation good?

  • Take s ahugh amount if energy to go from liquid to gas to provides a cooling effect when it evaporates
• What is cohesion tension theory?

  • Transpiration is water lost from leaves by evaporation
  • Cohesion is water molecules sticking together by hydrogen bonds
  • Adhesion is Water sticking to xylem walls
  • Tension is the negative pressure that pulls water up
