<li>Disorder is far more likely than order, which can be seen statistically.</li>
<li>The entropy of a system in a given state (a macrostate) can be written as

where \(k=1.38×{10}^{–23}\phantom{\rule{0.25em}{0ex}}\text{J/K}\) is Boltzmann’s constant, and \(lnW\) is the natural logarithm of the number of microstates \(W\) corresponding to the given macrostate.</li>

Summarizing Statistical Interpretation of Entropy

Physics is a science discipline concerned with the nature and properties of matter and energy. Physics topics include mechanics, heat, light and radiation, sound, electricity, magnetism, the structure of atoms, and so on.
