Facts about water???????

Question

need some please help/

Answer 1

75 % of the earth is covered with water.

97 % of earth’s water is in the oceans. Only 3 % of the earth’s water can be used as drinking water. 75 % of the world’s fresh water is frozen in the polar ice caps.

Although a person can live without food for more than a month, a person can only live without water for approximately one week.

The average person in the United States uses 80 to 100 gallons of water each day. During medieval times a person used only 5 gallons per day.

About 1.2 billion gallons of potable water are used in New Jersey each day.

87 % of New Jersey’s population obtains its drinking water from a public water system and 13 % from private residential wells.

It takes 2 gallons to brush your teeth, 2 to 7 gallons to flush a toilet, and 25 to 50 gallons to take a shower.

It takes about 1 gallon of water to process a quarter pound of hamburger.

It takes 2,072 gallons of water to make four new tires.

Sources of water pollution include: oil spills, fertilizer and agricultural run-off, sewage, stormwater, and industrial wastes.

Ancient Egyptians treated water by siphoning water out of the top of huge jars after allowing the muddy water from the Nile River to settle.

Hippocrates, known as the father of medicine, directed people in Greece to boil and strain water before drinking it.

In the 1950’s scientists began to suspect that water might carry diseases. Although earlier treatment of water could make the water safer, it was mainly done to improve the taste, smell or looks of the water.

The first United States water plant with filters was built in 1872 in Poughkeepsie, New York.

In Altona, Germany in 1892, the water from the Elbe River filtered before drinking. At the time, hundreds of people from nearby Hamburg (which did not filter their water) died from cholera. The citizens of Altona were untouched by this waterborne disease.

In 1908, Jersey City, New Jersey and Chicago, Illinois were the first water supplies to be chlorinated in the United States.

The Safe Drinking Water Act (SDWA) of 1974 represents the first time that public drinking water supplies were protected on a federal (national) level in the United States. Amendments were made to the SDWA in 1986 and 1996.

New Jersey Legislature approved the New Jersey Safe Drinking Water Act, which authorized the New Jersey Department of Environmental Protection to assume primacy and enforcement responsibility for the Federal Safe Drinking Water Program.

One gallon of water is equal to 3.785 liters of water.

One cubic foot of water is equal to 7.48 gallons of water.

Water boils at 212° Fahrenheit or 100° Celsius.

Water freezes at 32° Fahrenheit or 0° Celsius.

Answer 3

its called H2O, it is liquid, if you separate the oxygen from the hydrogen, the hydrogen becomes really explosive. It quenches your thirst. and it may make you p**s a lot if you drink too much.

Answer 4

Pure water does not conduct electricity but water almost always contains electrolytes that conduct electricity so keep the TV out of the bath tube.  

Answer 5

water is two hydrogen atoms combined with one oxygen atom

Answer 6

It has a high specific heat capacity (4.18J/K/g), which allows it to absorb much heat energy without actually heating up.

It has good thermal conductivity, which allows it to keep its temperature fairly stable.

It can hydrogen bond to itself and other molecules.

It boils at 100 degrees celcius and freezes at 0 degrees celcius.

Ice is less dense than water due to hydrogen bonding.

Water has fairly strong adhesion and cohesion, and high surface tension (this allows insects to 'walk' on water).

It is vital to life on Earth as it provides a solvent for many chemical reactions that occur inside the body.

Our bodies are made up of over 70% water.

And yeah, its 'wet'.

Answer 8

"Dihydrogen monoxide:

    * is also known as hydric acid, and is the major component of acid rain.

    * contributes to the Greenhouse Effect.

    * may cause severe burns.

    * contributes to the erosion of our natural landscape.

    * accelerates corrosion and rusting of many metals.

    * may cause electrical failures and decreased effectiveness of automobile brakes.

    * has been found in excised tumors of terminal cancer patients."

"Dihydrogen monoxide is colorless, odorless, tasteless, and kills uncounted thousands of people every year. "
