VI > I > V > III > VII > II > IV
First, we look at phases: gas > liquid > solid
So IV would be last.
Next, since everything else is a gas, we say that highest temperature and volumes lead to greatest entropy.
Rank these systems in order of decreasing entropy.
Rank from highest to lowest entropy. To rank items as equivalent, overlap them.
i) 1 mol of oxygen gas at 273 K and 40 L
ii) 1/2 mol of xenon gas at 100 K and 20 L
iii) 1 mol of xenon gas at 273 K and 20 L
iv) 1/2 mol of liquid xenon at 100 K
v) 1 mol of xenon gas at 273 K and 40 L
vi) 1 mol of carbon tetrachloride gas at 273 K and 40 L
vii) 1/2 mol of xenon gas at 273 K and 20 L
