Water

• What allows water molecules to have adhesive and cohesive properties


  Hydrogen bond
• What is a hydrogen bond

  an electrostatic attraction between the partially positive hydrogen atom and the partially negative oxygen atom of two adjacent water molecules
• Explain the polar nature of water

  oxygen is more electronegative than hydrogen, unequal share of electrons, electrons spend more time orbiting around oxygen than hydrogen, give regions of slight positive and slight negative
• state the name of the bond that holds water molecules together

  hydrogen bond
• Explain how water being a good solvent is important to living organisms 


  it allows chemical reaction to take place inside cells
• Explain how water having a high latent heat of vaporitasaion 


  cooling effect by evaporation of water/ sweat
• Explain how water has cohesion properties is important to living organisms 


  allows a continuous column of water to move through xylem vessels without breaking
• Explain how water having a high specific heat capacity is important to living organisms


  prevents internal temperatures changing quickly
