Water is one
of the basics of life on earth. Its reason is that without water, life is impossible
on earth. Moreover, to drink water is also helpful for our body in various ways
like it helps to create saliva, it regulates the temperature of the body, it
protects our tissues
and joints, it helps to excrete the waste material from our body, it helps to
maximize the physical performance of the body, it helps us to lose weight and
it can also enhance the circulation of oxygen in the blood. There are some
properties and facts about water. The properties and facts of the water are
given below;
Facts of Water
Water has
lots of amazing facts. These amazing facts of the water are given below;
Ø Water is the only natural substance
which is available in all the physical states i.e solid, liquid and gas.
Therefore, we can also say that water is a unique substance on earth.
Ø It is made of Hydrogen and Oxygen and
its chemical formula is H2O.
Ø The average amount of water in the
human body is from 50% to 65%.
Ø If we are asking water, it means that
we are referring to the liquid state of the water. On the other hand, the solid-state
of the water is known as ice and vapour state of the water is known as steam.
Ø Water also shows peculiar behaviour because
its solid form (ice) is less than its liquid form. That’s why
ice floats on the surface of the water.
Ø There is a huge amount of slat components
in the seawater. That’s why sea
water is salty. It is estimated that in every kilogram of seawater, there are
35 grams of salt.
Ø The presence of the salt components
in the water increases its freezing point. That’s why the freezing point of seawater
is 2 °C rather than 0
°C.
Ø The average amount of water in newly
born babies is up to 78%.
Ø The water cycle is responsible for
the maintenance of water resources in the world. The water cycle means that
water is evaporated from the surface of oceans, rivers and lakes and it goes into
the atmosphere. In the atmosphere, it condenses and falls on the earth in the
form of rain and ice. The ice on the surface of the mountains melts and it
forms rivers. We are using the water of rivers for various purposes. The rest
of the water again goes into the ocean.
Ø There is no smell and taste of the
pure water.
Ø At 0 °C, water freezes. On the other hand, at 100 °C, it evaporates.
Ø We need water to save our body from dehydration.
The need for the water for your body also changes. It means that in the summer,
we require more water than in the winter. Our activities also decide the need for
water.
Ø The weight of a gallon of water is
8.34 pounds. If we cover an acre of the earth with one inch of water, its weight
will be 27,154 gallons.
Ø The most important use of water is in
the form of agricultural irrigation. It means that we are fulfilling the water
needs of crops via artificial ways.
Ø Water is also known as a universal
solvent. Its reason is that water can dissolve more substances than any other
liquid. Therefore, either water is present underground or in our body, it
contains lots of minerals and other nutrients.
Ø We are also using water in the
hydroelectric power generations to generate electricity. There are lots of
hydroelectric power generations are available in the world. To generate electricity
from the hydroelectric power generations is known as the cheapest way to
generate electricity.
Ø More than 70% of the earth’s surface
is covered with water.
Ø The pure water is not acidic nor
basic because it has a PH scale 7. On the other hand, acids have a PH scale less
than 7 and bases have a PH scale more than 7.
Ø The 90% of the earth’s water is salty
which is present in the form of lakes and oceans. On the other, the rest of the
water is trapped in the earth or the glaciers.
Ø Water has also high cohesive
properties. That’s why water is very sticky liquid and it can easily stick to
the molecules of other substances.
Ø The amount of water in the atmosphere
is more than the water in the rivers.
Ø Pure water is not found in the
natural environment. It is also an amazing fact that pure water can’t conduct
electricity. Therefore, when some substances are added into the pure water, it
starts to conduct electricity.
Ø If all the water vapours that are
present in our atmosphere fell on the surface of the earth at once, these water
vapours will cover the surface of the earth up to one inch.
Ø The heat index of the water is also
very high. It means that it can absorb a large amount of heat. That’s why it is
very valuable in the industries and for the radiators of cars.
Ø If a faucet is dripping and it dips
one drop of water in one second, it will waste 3,000 gallons of water in one
year.
Ø The surface tension of the water is
also very high. Due to the high surface tension of the water, it tends to clump
together in the form of drops rather than in the form of a thin film. The high
surface tension of the water also allows the water to move through the roots of
the plants and blood vessels.
Ø More than 748 million people in the
world don’t have access to the fresh resources of water.
Ø Air pressure also affects the boiling
point of the water. At the higher altitude, the air pressure is low and as a result,
the boiling point of the water is also lower.
Ø If you want to irrigate one calorie
of food, you will have to use .26 gallons of water.
Ø If you want to make a sheet of paper,
you will have to use 2.6 gallons of water.
Ø If you want to produce 2.2 pounds of
rice, you will have to use 2,641 gallons of water.
Ø To manufacture a new car, you will
have to use up to 39,000 gallons of water.
Ø Due to the water cycle, the amount of
water remains constant in the world. That’s why instead of lots of uses of
water, the amount of water is the same as it was during the creation of the
world.
Ø The amount of water in the human
brain is almost 75% and the amount of water in a living tree is also 75%.
Ø Without food, a person can live alive
for more than one month. On the other hand, without water, it is almost
impossible for a person to live alive for more than one week.
Ø As we know that most of the people in
developing countries can’t have access to the fresh resources of water. That’s
why more than 80% of the diseases in developing countries are due to the
drinking of impure water.
Ø Water also plays a vital role in
regulating the temperature on earth.
Ø If we collect the whole water
resources on the earth in a four-litre jug, the amount of the freshwater will
be equal to a tablespoon.
Ø NASA has also discovered water
resources on the Moon but these water resources are found in the form of ice.
Ø If you are taking shower for 5 to 10
minutes, it means that you are using 10 to 25 gallons of water.
Ø The sun evaporates almost a trillion
ton of water every day.
Ø If you are suffering from a fever,
you should try to drink as much water as you can. Its reason is that by drinking
a huge amount of water, you can regulate the temperature of your body.
Ø 1.7% of the earth’s water resources
are permanently frozen. Therefore, these resources of water are not useful for
us.
Ø US residents are using almost 400
billion gallons of water daily.
Ø By drinking impure water, almost 200
children are dying every hour.
