# Arrange the following sets of systems in order of increasing entropy. Assume one mole of each substance and the same temperature for each member of a set. (Include states-of-matter under the given conditions in your answer. Use the appropriate symbol to separate substances in the list.) (a) F2 (g), Ne (g), H2 (g)

The question has some details missing, however here is a sample question; a) AgCl (aq), Ag (s), Cl2 (g)

b. Hg (l), Hg (s), Hg (g)

Explanation:

Entropy is the degree of randomness or disorderliness of a system. the S. I unit of entropy is J/K. Entropy increases from the solid to liquid to gaseous state, similarly it decreases from gaseous to liquid to solid.

You can use the same approach to attempt any question of such.

Increases in entropy is in the order gaseous > Liquid > solid

as such; Cl2 (g) > AgCl (aq) > Ag (s)

Similarly for Hg (l), Hg (s), Hg (g)

In the order; Hg (g) > Hg (l) > Hg (s)

And sometimes comparison is done using their standard entropy values from literature, the one will the higher standard entropy will have a higher increase.
