Saturated water substance table

[PrintScaffold]

Greetings everybody!

I need help with explaining "Saturated water substance" table from Marks' standard handbook, page 4-44.

Thermodynamics is completely outside of my field of work, I'm just trying to help my friend with his research for which he needs various data.

There are several columns in that table - temperature, pressure, and then columns for specific volume, enthalpy and enthropy that come in two different variations each - with lower-case indexes "c" and "g". What does that mean? Various conditions or what? Could anybody help me?

Thanks!

I don't have the book, but it appears that c means condensed phase and g means gaseous phase. The tabulated properties are those of the liquid and vapor phases in equilibrium at the given temperatures and pressures.
