Statistical Mechanics:<br />

The goal of statistical mechanics is to begin with the microscopic<br />

laws of <strong>physics</strong> that govern the behaviour of the constituents of<br />

the system and deduce the properties of the system as a whole,<br />

egs.<br />

1. Why are the properties of water different from those of steam,<br />

2. How are the molecules arranged in a liquid?<br />

Statistical mechanics is the bridge between the microscopic and<br />

macroscopic worlds.<br />
