To see this divide a container two and suppose that 1 half contains 20 molecules and the other none. What we expect to happen is for the molecules to spread out and have roughly half (10) in each half of the container. We can calculate the number of micro-states, <math>w</math>, which correspond to each macro-state: | To see this divide a container two and suppose that 1 half contains 20 molecules and the other none.
