I have already told that the efficiency of an ideal engine is [ 1-T'/T ] and no other engine (all other engines are real ones) have more efficiency than this one.
One of my fellow readers have asked a silly doubt,"this is all about engines right?" Yes,but an engine means a thermo dynamical observational system. This phrase doesn't digest for common people that's why I used 'engine',and it not only represent an engine of a machine or an automobile but every heat taking - giving systems.
So,there can't be more efficient engine than a ideal one. (if you have confusion about ideal and real one, think like this. Legends are ideal characters,but in real life we can't find any,as every people are real ones. There isn't any ideal legends,everyone should have any singles flaws or defects),as per the equation, the maximum value for efficiency is 1 and minimum is ofcourse 0. (how did this come? ,see the image)
What if then, the temperature becomes negative? (see the image), the efficiency is greater than 1. We just said, 1 is the maximum value and that is too ideal... How can any system ever get more efficient than 1? How can one be more legendious than legend? How can you be more yourself than yourself? How can water be more watery?
So the concept contradicts reality,hence the assumed thing is not real or generally,the negative temperature in kelvin scale is impossible.
This doesn't mean negative temperatures are impossible,after all its just temperature and positiveness and negtiveness are what we attributed to them. And this is only valid in kelvin scale ,not in Celsius or Fahrenheit scale. Kelvin is the general scale,so that's how it become more important.
But what if,there is a particular case in which negative kelvin exists?
