How many liters of chlorine gas can one liter of liquid chlorine produce upon evaporation?

One liter of liquid chlorine can produce approximately 460 liters of chlorine gas upon evaporation. This phenomenon is due to the properties of chlorine, which is a gas at room temperature and pressure but is stored in a liquid state under pressure. When liquid chlorine evaporates, it expands significantly as it changes from the liquid phase to the gas phase. This expansion ratio is typical for many gases, where a relatively small volume of liquid can generate a much larger volume of gas. The specific number, 460 liters, reflects the physical and chemical behavior of chlorine under standard atmospheric conditions, demonstrating the dramatic change in volume that occurs when liquid becomes gas.

Understanding this principle is crucial in wastewater treatment processes, particularly when chlorine is used for disinfection. It's important for operators to manage chlorine carefully, as the gas produced can pose hazards if not handled properly.
