Explanation / Answer

1mol of He at 273K and 40L > 1mol of F2 at 273K and 40L > 1 mol of NO2 at 273K and 40L > 1mol of He at 273Kand 20L > 1/2 mol He at 273K and 20L > 1/2 mol He at 100 K and 20L > 1/2 mol liquid He at 100K

Reason:

* Entropy is the measure of disorderness. More is the disoder more is the entopy.

* For different physical states : entropy of Gas > liquid > solid

* Higher is the temperature higher is kinetic enrgy, so higher is the disorderness and hence higher is the entropy

* Higher is volume higher is the space available to random moment and hence higher is the entropy.

* Smaller the attractions among the molecules/atoms higher is the diorder and thus higher is the entropy.
