1. Adhesion
2.2 Water
Cells & Biomolecule
the force by which individual
molecules cling to
surrounding material and
surfaces.
Boiling point
2.2 Water
Cells & Biomolecule
the temperature at which the
vapour pressure of a given
liquid reaches atmospheric
pressure and thus starts to
boil (100°C for water).
Cohesion
2.2 Water
Cells & Biomolecule
the force by which individual
molecules stick together.
Freezing point
2.2 Water
Cells & Biomolecule
the temperature at which a
liquid solidifies (0°C for
water).

2. Specific Heat
Capacity
2.2 Water
Cells & Biomolecule
the amount of energy
required to raise the
temperature of water by one
degree Celsius (water has to
absorb 4.184 joules of heat
for the temperature of one
gram of water to increase by
1°C).
Hydrogen bond
2.2 Water
Cells & Biomolecule
a weak bond caused by
electrostatic attraction
between a positively-
charged part of one
molecule and a negatively-
charged part of another.
Hydrophilic
2.2 Water
Cells & Biomolecule
molecules capable of
interacting with water
through hydrogen bonding
(having an affinity for water).
Hydrophobic
2.2 Water
Cells & Biomolecule
molecules that lack an
affinity for water (water
insoluble).

3. Polarity
2.2 Water
Cells & Biomolecule
property of having distinct
and opposite charges
(poles).
Solubility
2.2 Water
Cells & Biomolecules the property of a substance
of being soluble (dissolved).
Solvent
2.2 Water
Cells & Biomolecule
a liquid in which substances
(or solutes) are dissolved to
form a solution.
