Water conducts heat around 25 times more efficiently than air.

It is commonly recommended to drink eight 8-ounce glasses, which equals about 2 liters, or half a gallon. Though, some experts recommend drinking a half-ounce to an ounce for each pound of your body weight.

Water covers 71% of the Earth's surface. It is vital for all known forms of life.
8b
Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products. A greater quantity of water is found in the earth's interior.
8c
On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation.

9a
The most important use of water in agriculture is for irrigation, which is a key component to produce enough food.
9b
Water is heavily used to form solutions and mixtures for washing processes. A number of industrial processes rely on reactions using chemicals dissolved in water. Washing is also an important component of several aspects of personal body hygiene.
9c
To function properly and regulate body temperature, the human body requires between one and seven liters of water per day to avoid dehydration.
9d
The evaporation of water carries heat away from fire. Because of this, water is very useful as a fire extinguishing fluid.
9e
The use of water plays a critical role in the world economy. The transportation of materials through rivers and canals by means of cargo ships and tankers fosters international shipping and trading.

The distillation method can be used to convert salt water into clean drinking water. This process basically brings the salt water to a boil, causing the water to evaporate, leaving the salt and other chemicals behind. The evaporated water is then captured and recondensed by cooling to form fresh drinking water.
- Place a clean cup (such as a ceramic mug) in the center of a deep pot.
- Pour salt water into the pot, being sure to not add so much as to cause the mug to float. Be careful not to get any of the salt water in the mug
- Place a lid upside-down on the pot so that the handle faces down over the mug.
- Bring the water to a boil.
- As the water boils, it will evaporate and condense on the lid as liquid water. This water will then drip from the lid into the mug.
- Do not let all of the water evaporate from the pot.
- Turn off the heat and allow to cool before touching the mug.
