What is Entropy ?!!

My discussion ... 

- Entropy measures the ability of molecules and paricles network shape and order change ... !!

as much as molecules can be disordered and change places and more freely to move .. as much as high

Entropy !!



- The more system is shaped ... the more entropy it has ...

- Liquid >>> Gas  ............. low entropy to high entropy .............. change of entropy >>>  +ve !! 

- Solid >>>>Liquid  ..........low entropy to high entropy .............. change of entropy >>>  +ve !! 



Entropy increase when ... : 

Something dissolved ....

Temperature Increase ....

Gas Formed ...

More Moles Formed ....

As presseure decrease ... entropy  INCREASE !!

THE GAS HAS THE MOSTT ENTROPY !!!
