## gas with 2x positions

isochoric/isometric: $\Delta V = 0$
isothermal: $\Delta T = 0$
isobaric: $\Delta P = 0$

### gas with 2x positions

Why does each gas molecule have 2x positions available to it and therefore resulting in W2/W1=2 ?

This is set in the two-state system scenario.
When 2 particles are both in one of two states, then W = 4 = 2^2
If there is only 1 particle, then W = 2^1
So for N particles, a particle can be in one of two states, then W = 2^N

### Re: gas with 2x positions

The equation is the number of possible states (In this case, 2) raised to the number of particles. If there were three possible states, it would be 3^n, and so on.
