A Qualitative Description of Entropy

At this point, it is useful to introduce the mathematical definition of entropy proposed by Ludwig Boltzmaim  

Student Annotation The Boltzmann constant is equal to the gas constant, ft (in J/K mol), divided by Avogadro s constant, Na. 

Student Annotation The number of possible arrangements is sometimes called the number 

Student Annotation The state with the largest number of possible arrangements has the greatest entropy. 

One molecule on each side (eight possible arrangements)
