Term
Water
Definition
H2O
Polar-Covalent Bond
Term
7 Properties
Definition
Cohesion
Adhesion
Surface Tension
Heat/Temperature
Specific Heat
Vaporization
Density
Term
Cohesion
Definition
linking of water molecules to other water molecules due to Vaan der Waals (millions of weak hydrogen bonds)
Term
Adhesion
Definition
Linking of water molecules to other substances due to weak hydrogen bonds
Term
Surface Tension
Definition
caused by cohesion
Term
Heat/Temperature
Definition
used to monitor temperature because it can absorb large quantities of energy (heat) due to its millions of little hydrogen bonds. means that sweating will release a shit ton of excess heat
Term
Specific Heat
Definition
Amount of heat needed to break the bonds of a molecule.
Because of water's millions of bonds, its pretty high.
Term
Evaporization
Definition
mainly evaporative cooling. Because water contains insane amounts of energy/heat, the more you loose it the less heat you have--> aka sweating you lose heat
Term
Density
Definition
Water is pretty special. Because of its polar relationship with hydrogens, when in liquid form, H2O is actually denser than in solid (ice) form.
Term
Hydrophilic
Definition
dissolves in water
Term
Hydrophobic
Definition
Does not dissolve in water (oil)
Term
Molarity
Definition
The number of moles of solute per liter of solution
Term
pH scale
Definition
ACIDS (H+) 0-6
BASES (OH -) 8-14
NEUTRAL 7
