How to make 1N and 1M H2SO4 ?

Now let's see how to make 1 N and 1M  H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4.  If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl  / density                             98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N  H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula  1M H2SO4 (98%) =  53.30 ml [ V ]                100%    ...

Why is the sky blue colored ?

  Everytime when we look up then we see blue sky.

            


   Do you know, why ? 
          
     That is all happens because of scattering of blue light. We all know the range of visible region.
        
         



 Red, orange, yellow colours have high wavelengths, but they have low energy and frequencies. Because of that low frequencies, that colours can't scatter just like blue and violet colours. And that is why they travel lot of distance. Frequencies of colours varies from red to blue and blue to red.
    
        In other hand blue, violet, colours has low wavelengths but they have high energy and frequencies. And  Scattering of light is totally depend on frequency of colours. Violet and blue colours has high frequencies. our atmosphere contain different types of particles. That particles helps violet and blue colours to scatter. 

                    



        Violet colour has more energy and frequencies than blue colour eventhough sky looks blue  because our eyes are more responsive for blue colour.

Why Birds don't get Electrocuted on Power Cables?

        E lectricity is the flow of electrons through conductors. It always takes the easiest route, i.e., electricity always flows through a path of least resistance.      electricity flows are made of copper. Copper offers least resistance and is a very good conductor of electricity. However, the bird's body offers greater resistance and is not a good conductor as copper. Hence, electricity ignores the bird and flows through the cables and birds don't get electrocuted.      B esides this, electricity flows from its highest potential to its lowest potential. Now, the power cables usually run at different potentials. If bird's feet are on the same power cable, then they are at same potential. Thus, the bird doesn't get electrocuted. However, when the bird touches two cables with different potentials at the same time, then electricity will flow through the bird to go to the other cable with lower potential and the bird will get electrocut...

HOW CAN ANIMALS AND BIRDS SEE IN DARK ?

    Almost all animals and birds can see in dark. But humans cann't  see in dark or in night clearly. Just because of that ability to see in dark, some animals and birds can servive easily in this word ( owls). We all know they can see during day too, but ability to see in the dark make them special than humans.     Let's see how they can see in the dark .   The animals which can see in dark called as nocturnal animals. Nocturnal means ability to see in the dark. They can see in the dark just because of there eyes structure. Nocturnal animals eye contain specific rods cells that carry rhodopsin in the eyes that helps in the night vision. that rhodopsin are very sensitive to longer red wavelength.         Retina is the composition of rods and cones. Rods are not able to capture light as sharply as cones do. but That rods are very sensitive to low light level and hence responsible for the vision in night. Different animals have d...

Why is excess sugar dangerous for humans health ?

   If we consume a lot of sugar, then it can lead to serious health problems. For example: Image of sugar  A hormone called leptin tells our brain when to stop eating. However, consuming excess fructose which is a type of sugar can cause leptin resistance, a condition in which our brain does not respond to leptin. Hence, we overeat, resulting in obesity. Moreover, excess sugar is converted into a type of fat called triglycerides. Triglycerides can enter the bloodstream and form fatty deposits or plaques in blood vessels, increasing the risk of heart attack and stroke etc.  Image of heart attack  Excess sugar can even bind to collagen and elastin in our skin, damaging them and thus, making our skin saggy and wrinkly. Image of saggy and wrinkly skin .   Studies have also shown that women who have one or more sugary drinks per day are more likely to develop diabetes. Image of sugary drink. That's why  we need to stop consuming excess  sugar than...
