Skills
- Compare the thermal properties of water with those of methane and explain how this affects its use as a coolant in sweat.
- Compare the solubility of glucose, amino acids, cholesterol, fats, oxygen and sodium chloride in water and link this to the way they are transported.
- Explain benefits of water properties to living organisms (Transparency and density not required.)
- Evaluate how significant hydrogen bonding is in the properties of water
