Water

• Structure of water 


  .

  
• Explain how water has a high heat capacity

  It takes a lot of energy to break Hydrogen bonds

  Energy is used whilst trying to break the bonds therefore temp doesn't change and water acts as a buffer

  This helps animals maintain habitats
• Explain how water is a metabolite

  Water allowsetabolic reactions ro take place

  Eg : hydrolysis, condensation
• Explain how water has a large latent heat of vaporisation 


  It takes a lot of energy to break the Hydrogen bonds

  Energy is used to change liquid to gas when it evaporates carrying away the heat energy

  This helps animals cool down quicker
• Explain how water is a solvent

  Water has polar properties allowing ions to dissolve for transport this can make transport quicker for faster reactions
• Explain how water is polar

  Water is a solvent meaning it can dissolve ions and transport them for a faster reaction
• Explain how water is cohesive

  Attraction between water molecules creates a column for support

  Water has a high surface tension when in contact with air
• Explain how water is more dense than ice

  In a solid state water molecules are arranged far apart lowering the density this can help create habitats eg : icebergs
• How is water amphipathic

  It has both positive and negative ions oxygen is negative and Hydrogen is positive
