The pressure at which liquid ammonia completely vaporizes in a sealed container.

If 800 L of liquid ammonia (400 Kg) in a sealed container is completely vaporized, a high pressure can be achieved. Can we measure values such as the temperature and pressure of liquid ammonia inside the steel cylinder?
A lot of pressure, depending on the ambient temperature

If you want to vaporize it completely, you must meet these two conditions: 1. There must be enough space for the liquid ammonia to vaporize. 2 The ambient temperature must be higher than its highest boiling point temperature. For detailed parameters, you can check the chart showing the boiling point of ammonia versus pressure. It is available in the document \"Nitrogen Fertilizer Process Design Manual – Physicochemical Data Volume\". The above are my personal opinions.
The vaporization of liquid ammonia requires heat, which comes from the outside environment (temperature difference); the pressure corresponds to the saturated vapor pressure at that temperature.
