TOPIC 2: MOLECULAR BIOLOGY

1. Cohesive

   Annotations:

   • - Water molecules tend to stick together
   1. transport medium
2. Adhesive

   Annotations:

   • - Water molecules can stick to other substances/molecules that are CHARGED or POLAR - Transport medium
   1. transport medium
3. Thermal

   Annotations:

   • - High specific capacity  - High heat of vaporisation - High heat of fusion - Because of hydrogen bonding
   1. coolant
4. Solvent

   Annotations:

   • - Water can dissolve many organic and inorganic substances - Because of polar attraction of large quantities of water molecules can sufficiently weaken intramolecular forces and result in the dissociation of the atoms
   1. transport medium
5. Surface Tension

1. Oxygen - negatively charged Hydrogen - positively charged
