Chemistry interesting facts about things that you face everyday
Now,
I am going to tell you about 12 interested things that is very important for
our general life and for our competitive exams....
§ 1.I think we all know the common salt, do you know from where we get
this. DW get it from sea water by the process of evaporation. Evaporation
is a process in which the liquid get
convert in to gaseous form at any temperature but less than its boiling
point.
§ 2.Matter
is constantly changing in our nature. Plant grow because of the change in matter
when matter change from soil and from air in to the matter of the food. As we
all know water falls from the sky and come to earth and again go to sky by the
evaporation and get condensed to form water.
§ 3.Do
you ever any idea that why are house is made up of bricks. Because we know that
the bricks are made up of solid, and solid never get change their shape
and volume that is why we use bricks to construct the buildings
§ 4.Now
again we have the new interesting facts that is the nitrogen gas become
liquid at -196degree celcius.This gas is very important because this is use to
freeze the material and food instantly.
§ 5.Hydrogen
gas is the lightest gas and get diffuse faster than the heaviest gases. According
to Graham law the rate of diffusion of gas is inversely the square root of
density
§ 6.We
are familiar with plasma word in these the electricity conducts because of the
charges particle present in this.
§ 7.Why
the snow skiers press their knees to run.They press their knees because by
pressing , some snow get converted in to liquid which make them easier to
slide.
§ 8.
Now again we have the important subject that what is triple point. When the
temperature co exist the all three state of water
§ 9
.Why we use ice rather then water during the burning of skin . It is because of
latent heat of fusion, when the skin is injured by some reason then the people
use ice because the ice taken excess heat from skin.
§ 10
.Why the surgeons use to spray ether on a skin. Because ether has less boiling
point So it take heat from body and evaporate due to this the skin
get numb.
§ 11.When
the cricket player get injured during match, the ethyl chloride is
sprayed on the injured part as it take heat from body and then the
temperature become lower thus the player does not get much pain due to
numbness.
§ 12.Why
the cold drinks are also called carbonated drinks? That is because the cold
drinks are homogeneous mixture of carbondioxide gas in liquids water therefore
it called the carbonate drink.
§ 13.Why
the hot water is endangering for the aquatic animals?
Because
the hot water contain less amount of oxygen. That is the reason when the hot
water coming from the industries and factories is endangering the aquatic
animals and the cold water contains more amount of oxygen that is why animals
are happy to live in cold water.
§ 14.How
we can pass electricity through pure water? Because is covalent in nature
so,some acid or salts are added to make it conductor but rain water can conduct
electricity as it contains various acid.
Ø When there is lightning it produce ozone breaking o3 oxygen
molecule into its free radical and hence gives a smell after lightning Storm like chlorine.
Ø Gold and copper are the only two non silvery elements or metal.
Most metals reflect colours equally so the sun light is reflect as White. gold
and copper however absorb blue and violet light and leaves yellow light. copper
is the only metal that is naturally antibiotic.
Ø Water expands from its original size when it is freezes
while the other elements or not. that is because temperature describes atomic
vibration the more vibration the more space space it takes hence expansion but
there is an exception in water. even though it vibrates less when it is frozen,
the ice occupies more volume. that is due to the strange shape of molecules. if
you remember looks like Mickey Mouse the oxygen sitting at the centre like the
face of the mouse And two hydrogen like the Mickey's here. because of how
oxygen and hydrogen bond, the water molecule is an open structure with a lot of
space. is it release energy when it is freeze and so it takes more space and
thus it expand.
Ø water freezes faster than cold water.
Ø The age of hydrogen atom in your body is near about 13.5 billion
years old which is near about the age of universe because during the universe
singularly the very first chemical element was hydrogen.
Ø Super fluid helium is the only liquid that can climb on the
wall and define the gravity because at the temperature of 2.17k which is very
close to absolute zero zero viscosity fluid which will move rapidly through any
pour in the Apparatus .
Ø The level of water will go down if you power a handful of salt
into it that is due to the solvent molecule which becomes more ordered in the
vicinity of dissolved ion.
Ø Astatine is the only rarest naturally occurring element in the
earth crust
Ø 1 inch of rain is equal to 10 inch of snow
Ø Rubber tyre is technically one single giant polymerized molecule .
Ø Your car bags packed with Sodium Azide salt which is very toxic.
