Cold water
* Most cold water gets evaporation
  - removes heat
* Requires a cold water detergent to get clothes clean.
* Some cold water boosts metabolism
  - reduces productivity
* can also be a cause of spotting
  - leach metals while standing in pipes
  - cause a headache identical to that which is triggered by eating something cold
* can hold more DO than warm water
  - air than warm water
  - carbon dioxide in solution than warm water
  - dissolved oxygen than warm water
* can hold more oxygen than warm water
  - much more dissolved oxygen than warm waters
  - kill
  - quickly numb the extremities
* can shock or even kill root hairs
  - tiny seedlings into oblivion
* carries more oxygen that warm, so as it rises it re-oxygenates the upper layers
  - much more dissolved gas than warm water
  - oxygen better than warmer spring waters, and it also minimizes algae growth
* causes damage
  - stress and cold water standing in the crown causes crown rot and fungus
  - the body's temperature to drop
* closes the pores of the skin possibly trapping contamination inside.
* conducts heat from the body.
* contains more nutrients than warm water.
* cools the air above it, causing fog.
* dilates the blood vessels, causing the heart to pump harder.
* flows progressively through the collector where it is heated by the sun.
* has a greater capacity of dissolving oxygen that warm water.
* has more carbon dioxide than warm water
  - dissolved oxygen than warmer water
* heats up when warm water is added because of the second law of thermodynamics.
* helps the legs recover quicker - just like putting ice over an injury.
* holds more dissolved oxygen than warm water
  - gas than does warm water
* holds more oxygen than warm water and water holds less oxygen at higher altitudes
* holds more oxygen, and a greater variety of organisms
  - for example, than hot water
  - much more oxygen but the demand by organisms is lower
* hydrates the gelatin without letting it absorb too much liquid.
* improves immunity.
* is absorbed into the system more rapidly than warm water
  - more quickly into the system than warm water
  - out of the stomach and into the blood stream faster
  - added to the hot water stored in the tanks whenever hot water is removed
  - all it takes to dissolve Point Blue
  - also the enemy of manatee
* is best at cutting suds from clothing in the rinse cycle
  - for macroinvertebrates
  - to drink because it empties from the stomach and enters the blood quickly
  - denser and therefor heavier than warm water
* is denser than hot water and it tends to sink
  - water, because when water gets hot it expands
  - generally more dense than warm water, thus sinking and displacing warmer water
  - kept completely away from the skin and heat loss is limited
* is located in refrigerators
  - water fountains
  - mixed under pressure with air and sprayed into the below-freezing atmosphere
* is more Dense and therefore sinks
  - dense than hot water
  - much denser than warm water
* is the best and most economical fluid to drink to keep a person hydrated
  - fluid for exercisers
  - drink of choice when kids are active in the heat
  - used for cooling, the cafeteria, the washrooms, and laboratory use
* keep drinks chilled on the warmest days.
* kills, and depending on the temperature, it can kill fast.
* leaves the stomach far more quickly than room temperature water.
* limits blood loss from the easily damaged small blood vessels.
* makes redfish look for something warmer.
* provided in drinking fountains is also a factor in energy consumption.
* reduces pain of pressure or inflammation.
* requires more energy to boil than hot water.
* saves energy and solidifies grease, which can be ground up and flushed away.
* sinks off Greenland, circulates in a complex worldwide pattern.
* slows development while warm water speeds development.
* stimulates the nerves close to the surface of the skin and is rejuvenating.
