Essential Idea:
Water is the medium of life
Understandings:
- Water molecules are polar and hydrogen bonds form between them
- Hydrogen bonds and bipolarity explain the cohesive, adhesive, thermal and solvent properties of water
- Substances can be hydrophilic or hydrophobic
Applications:
- Comparison of the thermal properties of water with those of methane
- Use of water as a coolant in sweat
- Modes of transport of glucose, amino acids, cholesterol, fats, oxygen and sodium chloride in blood in relation to their solubility in water
