Why are entropy changes for N2, silver and water close in value?

[Corneo]

Can someone explain to me why the change in entropy for 1 mol of N2, silver, and water are all relatively close together? The values of the change in S I respectively are S=72.8060J/K, 102.1817J/K, 86.6032J/K, 108.8686J/K.

Yea to me they don't even look close together but they agree with the book's answer (assuming the book is correct).

N2, silver and H2O are the three substances but you have four values for S

Opps I forgot to mention Mercury is in there also. But that's not too important. I would like to know why their delta S are all "close"
