Entropy and the Second Law of Thermodynamics
Entropy (S) is a measure of disorder
A system with little freedom, such as a crystalline solid or a deck of cards in a specific sequence, has relatively small disorder and low entropy.
A system with many degrees of freedom (possible arrangements), such as a gas or a shuffled deck of cards, has relatively large disorder and high entropy.
Sdisorder > Sorder
_ Ssys = Sfinal - Sinitial
