WHAT IS THE THIRD LAW OF THERMODYNAMIC ?


In this article we are going to discuss about the " Third Law Of Thermodynamics" its statement is given by a chemist Nernst walther in 1912 .



STATEMENT - " The Entropy of a perfect crystal at absolute zero temperature is zero "

 
[since its impossible to attain absolute zero temperature in finite number of operation's] .


 CONCLUSION -

Although its impossible to attain absolute zero temperature because some internal energy always remains in molecules meanwhile refer this law as limiting behavior for any object .

FOOTNOTES -

* Entropy - measure of how much , molecules can move disorderly

Perfect crystal - perfect crystal has definite size and arrangement of its unit cell throughout 3 - dimension without any single defect . 

* Absolute temperature - "0 kelvin " or ( - 273.15 degree Celsius ) . it is a minimum temperature any object could have .

SUM OF INFINITE SERIES BY RAMANUJAN

I n this blog i am going to discuss about something very strange important but strange a master piece from a Indian mathematician Srinivasa Ramanujan , who who discovered something mind blowing .   So if i ask you what is the sum of all natural number more likely you will answer  "infinity" and like always genius personalities has something different opinion just like srinivasa Ramanujan . Lets see how                    1+2+3+4+5+6+7+8+9 . . . . . . Became  -1/12 Let's take a infinite series S1 -                     S 1 = 1-1+1-1+1-1+1-1+1-1+1 . . . . . . lets do little maneuver with it like we always do in mathematics -  S1 = (1-1)+(1-1)+(1-1)+(1-1)+(1-1)+(1-1). . . . . .  we are just taking brackets at first on "plus one" and than closing it after...

WHAT IS NANOTECHNOLOGY ?

N anotechnology is the science of manipulation of matter according to our need at the Nanoscale of the order of 10^-2 . it have tremendous possibilities in near future because of its ability of making advance material  with unique chemical property which suits according to condition   .  This term technically first time introduced by physicist Richard Feynman in 1959 in his lecture with topic of There is plenty of room at the bottom . but at that time technology was not enough to implementation of his idea in practical application's . Primarily there is two type of approaches we use to construct anything  - I)  Top-to-bottom approach  II) Bottom-to-top approach Top-to-bottom approach :- when we cutoff resource to make our desirable shape is known as Top-to-bottom approach ; Ex- wooden chair .  Bottom-to-top approach :- when we construct structure by starting from its minute cells to approaching required shape of structure is known...

WHAT IS LIGHT EMMITING DIODE ?

LED is a very commonly used device nowadays we use it in various application because of its small size and,cheap prize its very popular among peoples . we use it even in special television set for screen as LED pixels which is useful for clarity for distance audience . basically it is a diode which is set to be in forward condition .   Full form of LED is LIGHT EMITTING DIODE . As evident from name it is diode who produce photon when voltage is given to it . this type of diode is not made by generally used semiconductor's like silicon and germanium it manufactured by arsenic phosphorus and gallium . various types of color can can be produced by changing quantities of material it made up of .  WORKING - Basically it is like a normal diode just difference with it produces light when a forward voltage applied to it . as we know  electron needs energy to jump from lower orbit to higher orbit ,  the working of LED is typically reverse of this process electr...
