The state of ammonia (gas or liquid)
Thread Content
Is ammonia a liquid or a gas in a container at a pressure of 1.2 MPA and a temperature of 120 degrees? Please share your opinions; points will be given
At this condition, ammonia should be in gaseous state; ammonia will liquefy only at 891 Kpa and 20°C.
Ammonia begins to liquefy at 891 Kpa and 20°C; calculations show that it is in a liquid state at 1.2 MPA and 120°C.

Under this pressure, with a temperature below the critical temperature, it should be in a liquid state~
At 120°C, the saturated vapor pressure should be 90.9 barg. Below this pressure, a gas-liquid coexistence state exists, with the liquid phase being the dominant phase and a gas phase also present.
As for gas, it goes without saying; no need to thank me for that
Where there is liquid, there must be gas; gas and liquid are in saturation. In a liquid ammonia sphere tank, it will continue to vaporize as long as it has not reached its saturated vapor pressure.
