THINKING WITH CHEMISTRY...

 

                                                                                          When it comes to Chemistry,many people find it hard to realise its interesting and wonderful self as they are ignorant about its basics. They find Chemistry as a subject of boredom and pure 'byheart'ing.. I think Chemistry becomes something amazingly awesome if they jst make it a part of their life nd not jst something to learn at the last moment of their chemistry exm.. It is there where the basics of chemistry is so important.. By the heading im not here to explain the classical basic theories of chemistry lke the gas laws but to give u something basical to chemistry which will make u integrate ur surroundings with the science  nd appreciate its creativity in daily life........................

                                When u see a window glass try to appreciate its chemical composition.. It should come to u always that the whole universe specifically the whole things that u see in ur surroundings is made from just 118 types of atoms......just the trillions and trillions of permutations and combinations of it.... ... Isnt tht wonderful to know that diamond nd graphite have the same element carbon as its building block... Same way, when u find it very unpleasant to breathe near a polluted pond try to think of the compounds lke h2s which causes it due to th reduced dissolved o2 contnt in it...
                   a more interesting thing tht i would always think is tht imagine the atoms in your body... as normally we consider atoms to be non-destructable give sme time for thnking where did the atoms in your body come from... They came frm the food you ate... vegetables , meat, whatever it may be.or from your mother./ imagine where would it go after your death.. to the soil.. from where plants nd microbes take it. in course it reach any other living thing./................ Now comes the interesting part imagine the course of the atoms tht make you... may be some of them were present in marie curie or albert einstein or even an actual wild tiger.................................../

                           Chemistry should be learnt from its root... By seeing th world through a chemists eye u r not seeing but experiencing it........

SUBLIMATION

                                                                       





                                                                            In simple words Sublimation is the phenomenon in which a solid substance, on heating ,transforms directly to its gaseous form without exhibiting its liquid state. There are so many subsatnces exhibiting this phenomenan like camphor,iodine,incense stick,etc.
               
                                                            Sublimation has so many practical uses , one important being its use in separation of mixtures. The reason behind sublimation is  resides in the atmospheric pressure i.e. when we heat the solid substance that particles get energy to move. In normal cases the atmospheric pressure is enough to keep the particles in liquid state . But in the case of particles which sublimes this is not enough hence they go directly to gases phase rather than liquid state.
