### molecule:

Water molecule
* Many water molecules have their positive end attracted to an hydroxide ion.
* are able to escape from the Earth's surface fairly easily
  - attracted to each other because of their polarity
  - broken down into oxygen and hydrogen atoms
  - cohesive and adhesive
  - constantly on the move
  - disorderly and mobile only to a point, which is thirty-two degrees Fahrenheit
  - held together by bonds
  - hydrogen bonded to each other
  - more attracted to one another than they are to molecules in the air
  - much closer together than are the gas molecules in the air
  - polar, having slight positive and negative sides, which causes their cohesion
  - slow to respond to heat gain or loss
  - smaller than molecules of oxygen gas
  - sticky
  - the most abundant in the human body
* are too big to pass through and stay behind
  - small to see even with the most powerful microscope
* assemble and disassemble millions of times per second in very precise arrangements.
* attach to mineral grains.
* attract other molecules.
* can cling to themselves and hold on to each other by cohesion
  - escape only from the surface
* can form hydrogen bonds in the RO membrane and fit into the membrane matrix
  - with each other
* cause no critical contamination like oil, but they are hard to pump.
* condense around particles in the atmosphere.
* contain hydrogen atoms.
* contribute to the close packing, thereby mediating shape complementarily.
* display a strong tendency to form shells of hydration.
* form a shell around fat with which hydorgen bonds are impossible
  - an infinite hydrogen-bonded network with localized and structured clustering
  - clusters of varying sizes
* form hydrogen bonds with each other and are strongly polar
  - polar molecules, and each other
* has a positive and a negative side.
* have a high dipole moment and are joined together by means of a hydrogen bonding
  - polar structure
  - positive charge on one end and a negative charge on the other end
  - strong tendency to stick together
  - the ability to dissolve many solutes associated with cells
* join in and make the cleavage in a fraction of a second.
* like to stick to one another, like small magnets
  - other substances
* move from their fixed position
  - further apart when water freezes
  - in an orbital motion as the wave passes
  - randomly across the barrier with no net addition of water to either side
  - too rapidly in the gas phase to allow bonding between molecules
* occupy the axial positions.
* occur in nepheline, potassium feldspar, cordierite and other ring silicates.
* release latent heat during the condensation process.
* serve several vital functions within the cell.
* stick to each other through relatively weak bonds called hydrogen bonds.
* sticking to each other is how plants get there necessary water supply.
* tend to ionize or dissociate into hydrogen ions and hydroxide ions
  - move from a less negative potential towards a more negative potential
* travel up the xylem to the leaves due to the pressure difference within the xylem.
* vibrate back and forth in a ice cube, but move randomly in liquid and gas states.
+ Enzyme, Function: Biochemistry :: Molecular biology
+ Substrate (biochemistry): Biochemistry
  * The sucrase bends the sucrose, and strains the bond between the glucose and fructose. Water molecules join in and make the cleavage in a fraction of a second.

Moment
* Every moment spent with a child influences the development of their brain.
* are forces that cause an object to rotate about an axis
  - just the distance from a certain point at which a force acts
  - points
  - statistics
  - time
* measure of the tendency to produce rotation, especially about a point or axis.
* physical quantity related to the total energy released in the earthquake.

### moment:

Dipole moment
* are moments.
* is also a vector quantity
  - the charge times the distance of the two charges
