Chemistry Entropy Notes 1. What is entropy? How many ways can
... entropy of the system. Actually, because the number of arrangements of atoms/molecules/ions is huge, entropy (S) is defined as the natural logarithm of the number of arrangements (W) multiplied by a constant (k): S = k*ln(W) K is Boltzman’s constant, and the equation bears the name “Boltzman’s equat ...

Physical or Chemical Properties
... Physical Change With a physical change no new substance is created and the original matter can be recovered. Physical change does not change the composition of the matter. The original matter is still present. The substance may seem different, but the way the atoms are linked up are the same. ...
