Understandings:
2.2.U1 & NOS: Water molecules are polar and hydrogen bonds form between them
2.2.U2: Hydrogen bonds and bipolarity explain the cohesive, adhesive, thermal and solvent properties of water
2.2.U3: Substances can be hydrophilic or hydrophobic
Applications:
2.2.A1: Comparison of the thermal properties of water with those of methane
2.2.A2: Use of water as a coolant in sweat
2.2.A3: Modes of transport of glucose, amino acids, cholesterol, fats, oxygen and sodium chloride in blood in relation to their solubility in water
2.2.NOS Use of theories to explain natural phenomena- the theory that hydrogen bonds form between water molecules explain the properties of water.
