What is the atmospheric boiling point of Ammonia (Anhydrous NH3)?
Direct Answer
Option A: -33.4°C
Anhydrous ammonia boils at -33.4°C at atmospheric pressure. As mandated by the IGC Code, understanding exact physical properties is critical for containment system design, pressure-temperature relationships, and selecting appropriate reliquefaction or refrigeration cycles during transport to prevent overpressurization.
