Resource summary

Water
1 Thermal properties:
1.1 High specific heat capacity; Hydrogen bonds
1.2 High boiling point
1.2.1 100 Degrees
1.3 Excellent coolant e.g sweating, panting
1.4 Aquatic life can still live under ice; water is densest at 4 degrees- then shrinks
1.5 Requires lots of energy to seperate water + hydrogen molecules apart
1.6 Cohesive structure
1.6.1 The sticking together of particles of same substance.
2 Cohesive properties:
2.1 Water molecules stick together --> Hydrogen bonds
2.1.1 Water: dragged up via Xylem vessels to top leaves of trees
2.2 Surface tension
2.2.1 Living things can live on surface of ponds & streams e.g. pondskater
3 Solvent properties:
3.1 Universal solvent
3.1.1 Can dissolve many substances esp POLAR ones.
3.1.1.1 POLAR: Substances that have + & - charges in molecular structure.
3.1.2 Only HYDROPHOBIC substances DON'T dissolve in water
3.2 Metabolic reactions happen in AQUEOUS solutions
3.3 Many substances can be transported around if dissolved in SAP/BLOOD
4 Transports materials e.g. blood, sap
4.1 Supports plant structure
4.1.1 Used in photoshynthesis
4.1.1.1 6CO2 + 6H2O ------> C6H1206 + 6O2
4.1.1.2 Carbon Dioxide + Water -------> Glucose + Oxygen
4.2 Hydrogen (slightly +) attracted to Oxygen (slightly -) ---> Covalent bonding between them
4.2.1 Water is stable structure; numerous HYDROGEN bonds
4.2.2 Water structure is DIPOLAR
4.2.2.1 Electrically neutral molecule carrying + & - charge
