2.2 Water: Properties of Water and Benefits to Living Things

Understanding that:

- The theory that hydrogen bonds form between water molecules explains the properties of water
- Water molecules are polar and hydrogen bonds form between them
- Hydrogen bonding and bipolarity explain the cohesive, adhesive, thermal and solvent properties of water
- substances can be hydrophilic or hydrophobic
-there is a comparison between thermal properties of water and those of methane
- water acts as a coolant in sweat
- modes of transport of glucose, amino acids, cholesterol, fats, oxygen, and sodium chloride in blood depend on their relation to their solubility in water
