QUIZ ON WATER!

‘Water is the driving force of all nature.’

Leonardo da Vinci

1)CHOOSE THE CORRECT ANSWER:What’s the Water’s chemical formula?

a)HO b)H2O

c) OHd)ΗΟ2

And the correct answer is…..

b) H2O ! • Water is a chemical compound with the chemical

formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

2)CHOOSE THE CORRECT ANSWER:Which is the longest river in the world?

a)The Nile b)The Amazon c) The Yellow River d)The Danube

And the correct answer is…..

a) The Nile !• The Nile (is a major north-flowing river in northeastern

Africa, generally regarded as the longest river in the world. It is 6,650 km (4,130 miles) long. The Nile is an "international" river as its water resources are shared by eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Sudan and Egypt. In particular, the Nile River provides the primary water resource and so it is the life artery for its downstream countries such as Egypt and Sudan.

3)CHOOSE THE CORRECT ANSWER:What is the percentage of the drinkable water on the planet?

a)1%b)30% c) 3% d) 5.5%

And the correct answer is…..

c) 3% !• Drinking water or potable water is water safe

enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries, the water supplied to households, commerce and industry meets drinking water standards, even though only a very small proportion is actually consumed or used in food preparation.

4) CHOOSE THE CORRECT ANSWER:What’s the water’s boiling point?

a)50°Cb) 0°C c) 100°C

d)180°C

And the correct answer is…..

c) 100°C !• The boiling point of water depends on the

atmospheric pressure, which changes according to elevation. The boiling point of water is 100°C or 212° F at 1 atmosphere of pressure (sea level), but water boils at a lower temperature as you gain altitude (e.g., on a mountain) and boils at a higher temperature if you increase atmospheric pressure (lived below sea level).

5)CHOOSE THE CORRECT ANSWER: What’s the water’s freezing point?

a)1°Cb)0°Cc) 100°Cd)0°K

And the correct answer is…..

b) 0°C !• The freezing point or melting point of water

is the temperature at which water changes phase from a liquid to a solid or vice versa. Ordinarily the freezing point of water is 0° C or 32° F.

6)CHOOSE THE CORRECT ANSWER:What’s the percentage of water in our body?

a)72%b)75% c) 40% d)65.7%

And the correct answer is…..

a) 72% !• In physiology, body water is the water content of

the human body. A significant fraction of the human body is water. Bodily water percentage varies by gender, age and body structure. Infants and children contain the highest proportion of water, at approximately 77 percent. Adult males are 60 percent water, women are 50 percent water, and seniors usually have the lowest body water proportion, at 45 percent.

7)CHOOSE THE CORRECT ANSWER:How many liters of water must a human being

consume on a daily basis?

a) 2lts b) 1lt c) 1,5lts d)3lts

And the correct answer is…..

a) 2lts !• Everyone has heard the advice, "Drink eight 8-

ounce glasses of water a day." That's about 1.9 liters, which isn't that different from the Institute of Medicine recommendations. Although the "8 by 8" rule isn't supported by hard evidence, it remains popular because it's easy to remember. Just keep in mind that the rule should be reframed as: "Drink at least eight 8-ounce glasses of fluid a day," because all fluids count toward the daily total.

8)CHOOSE THE CORRECT ANSWER:Which is the most water consuming country?

a)Chinab)Greecec) Russiad)USA

10)CHOOSE THE CORRECT ANSWER:What is water used in urban areas for?

a)Personal Hygieneb)Farmingc) Drainage

And the correct answers are…..

a) Personal Hygiene and c) Drainage

• Hygiene is a set of practices performed for the preservation of health. While in modern medical sciences there is a set of standards of hygiene recommended for different situations, what is considered hygienic or not can vary between different cultures, genders and etarian groups. Some regular hygienic practices may be considered good habits by a society while the neglect of hygiene can be considered disgusting, disrespectful or even threatening.

11)CHOOSE THE CORRECT ANSWER: What is the human in the picture suffering from?

a)Xerodermiab)Skin

infectionc) Dehydration

And the correct answer is…..

c) Dehydration !• In physiology and

medicine, dehydration (hypohydration) is the excessive loss of body water, with an accompanying disruption of metabolic processes. It is literally the removal of water (Greek: ὕδωρ, hýdōr) from an object; however, in physiological terms, it entails a deficiency of fluid within an organism. Dehydration of skin and mucous membranes can be called medical dryness.

2)An oil spill is destroying the sea life and water. !

• Oil spills make up about 12% of the oil that enters the ocean. The rest come from shipping travel, drains and dumping. An oil spill from a tanker is a severe problem because there is such a huge quantity of oil being spilt into one place. Also, Oil spills cause a very localized problem but can be catastrophic to local marine wildlife such as fish, birds and sea otters.

water !• Water conflict is a term describing a conflict between countries,

states, or groups over an access to water resources.[ The United Nations recognizes that water disputes result from opposing interests of water users, public or private. A wide range of water conflicts appear throughout history, though rarely are traditional wars waged over water alone. Instead, water has historically been a source of tension and a factor in conflicts that start for other reasons. However, water conflicts arise for several reasons, including territorial disputes, a fight for resources, and strategic advantage.

And the correct answer is…..

2) Ex- farmable piece of land !

• Drought is an extended period of months or years when a region notes a deficiency in its water supply whether surface or underground water. Generally, this occurs when a region receives consistently below average precipitation. It can have a substantial impact on the ecosystem and agriculture of the affected region. Although droughts can persist for several years, even a short, intense drought can cause significant damage and harm the local economy.
