Basic building block of all matter. A microscopic sphere composed of smaller particles.
Protons, Neutrons
found inside the nucleus of an atom
Surround the nucleus
A group of two or more atoms held together by mutually shared electrons
Covalent bonds
the bond created when two atoms share electrons. (very strong)
the Slight separation of charges that gives the entire molecule a positive or negative charge.
When molecules tick to each other. Causes to surface tension.
The process in which water molecules completely surround ions
Van Der Waals forces
relatively weak interactions that become significant only when molecules are close together as in the solid and liquid states.
the energy of moving molecules
kinetic energy
moving energy
the amount of heat required to raise the temperature of 1 gram of water by 1 degree.
the direct measure of the average kinetic energy of the molecules that make up a substance.
latent heat of melting
the enrgy needed to break the intermolecular bonds that hold water molecules rigidly in place in ice crystals
latent heat of evaporation
the amount of heat it takes to produce 1 gram
latent heat of codensation
when water vapor is cooled sufficiently, it condenses to a liquid and releases its latent heat of condensation into the surrounding air
latent heat of freezing
the amount of heat released when water freezes is the same amount that was absorbed when the water was melted in the first place.
Marine effect
describes locations that experience the moderatiing influences of the ocean, usually along coastlines or islands.
continental effects
refers to areas less affected by the sea and therefore havinga greater range of temperature
thermal contraction
shrinkage caused by cold temperature
total amount of solid material dissolved in water. the ration of the mass of dissolved substances to the mass of water sample.
principle of constand proportions
major disolved constituents responsible for the salinity of sea water beig the same nearly everywhere in the ocean in the exact same proportions.
the weight of an ion in a water sample
brakish water
somewhat saltish water produced where freshwater and sea water mix.
a curve that shows the density
a curve that measures temperature
curve that majors changing salinity with depth
the process that keeps the ph level of seawater constant
residence time
the duration a dissolved subtance stays in the ocean
hydrologic cycle
the cycle in which water moves from the ocean to the clouds to the earth and back into the ocean.
