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.
