Water Properties Flashcards
Water is STABLE / UNSTABLE with COVALENT / NON COVALENT bonds
STABLE, COVALENT
Water has HIGH / LOW heat capacity
HIGH
Water’s high heat capacity has what effect on the environment and animals?
It moderates seasons, and creates thermal stability for sea creatures
Water takes LOTS OF / NOT VERY MUCH OF latent heat
LOTS OF
Water has a HIGH / LOW freezing point and a HIGH / LOW melting point
HIGH, HIGH
What does the structure of water indicate to us about it’s properties?
It should be a gas at room temperature. The fact that it is a solid is one of the biggest allowances for life on earth
Pressure DECREASES / INCREASES boiling point
increases boiling point
Salinity DECREASES / INCREASES boiling point
decreases boiling point
Why does water become more light as it freezes?
the crystalline structure is much less dense than an amorphous structure.
What effect does high viscosity have on sea creatures?
High viscosity causes evolutionary pressure to become streamlined. It also changes with temperature, causing buoyancy of sea creatures to change with temperature.
Water is a BAD / GOOD solvent
GOOD
Water has HIGH / LOW surface tension
HIGH
Hydrophilic means that cohesion is HIGHER / LOWER than adhesion
LOWER
Hydrophobic means that cohesion is HIGHER / LOWER than adhesion
HIGHER
what is a neuston?
A creature that uses the air-water interface
