liquid ammonia

Liquid ammonia is ammonia gas cooled under pressure until it turns into a transparent, colorless liquid. It is commonly used in industrial applications, such as fertilizer production and refrigeration. When cooled, ammonia's molecules are packed closely together, making it a dense liquid, but it vaporizes easily back into gas at normal temperatures. It has a pungent smell and is both useful and hazardous—requiring careful handling. In its liquid form, ammonia serves as a key raw material in producing nitrogen-based chemicals vital for agriculture and other industries.
