How to determine the phase state of a substance
Thread Content
At a certain temperature and pressure, it’s not clear whether a substance is in a gaseous or liquid state; where can one find phase diagrams or how can this be calculated? Thank you to all the experts
Could the expert be more specific? What software is it, and how does one operate it?
If you search for data or curves related to saturated vapor pressure and cannot find what you need, try checking whether the Antoine equation provides the necessary parameters; this can be used to calculate the saturated vapor pressure. If the pressure is higher than the saturated vapor pressure, it is a liquefied gas; if it is lower, it is a pure gas
