| Jul 3, 2021 at 19:12 | comment | added | Anmoldeep | I couldn't comment because I have less reputation to do so, but I wanted to suggest looking at this text here chem.libretexts.org/Bookshelves/… Although it worked in your case, all roots may not be identical and at subcritical temperatures, 2 of the 3 roots (if real), do have a physical significance | |

added temperature criteria

| Jul 3, 2021 at 13:32 | comment | added | Vamsi Krishna | @IvanNeretin Okay makes sense if we consider phase transitions. But what if we confine our discussion to only gases, i.e, set the temperature above the critical temperature? | |

mathrm m, units of a are wrong

| Jul 2, 2021 at 19:16 | comment | added | Ivan Neretin | You must have heard about the phase transitions. Scenario 1: you have 9 moles of water and 1 mole of saturated water vapor. Scenario 2: you have 1 mole of water and 9 moles of vapor at the same pressure. Is volume the same in both scenarios? | |
