Strange question about chemistry and standard entropies?

[Jessica R]

Standard entropies for substances as given in many books are defined at a pressure of exactly 1 bar. In many other texts, the standard pressure is set at exactly 1 atm (760 torr).

For gases, this correction factor would be _______ J/mol·K. (The answer must be exact to 6 significant figures with the proper sign attached. )

Would this apply to solids and liquids? (Answer: Y or N).

[GuitarChemist]

Well, although gases are the major consideration when working with entropy values, liquids do have an appreciable level of disorder. Solids, however, have negligible entropy, and aren't really taken into consideration. So in response to your question, the correction factor would be so small for solids, whose entropy is tiny anyway, that it may as well be ignored, whilst for liquids, if working to six significant figures, you might well encounter a decent value for the difference in entropy at 1bar and 1atm exactly.
