At normal atmospheric pressure, liquid chlorine (Cl₂) begins to vaporize at what temperature?

• A. 0⁰ F
• B. 20⁰ F
• C. -29.29⁰ F
• D. 10⁰ F

Answer: (C)

Liquid chlorine begins to vaporize at approximately -29.29°F at normal atmospheric pressure. This is due to chlorine's physical properties and its phase transition from liquid to gas, which occurs at this temperature under standard atmospheric conditions. In the case of chlorine, it has a relatively low boiling point compared to many other substances, reflecting its volatility as a gas at room temperature and pressure. The behavior of chlorine as a gas above this boiling point makes it commonly used in applications such as disinfection and water treatment, where it must be handled with care due to its hazardous nature. Understanding this phase change is essential in wastewater treatment, as chlorine plays a vital role in disinfecting wastewater before it is released into the environment. Knowing the behavior of chlorine at different temperatures is crucial for safe and effective usage in various applications within wastewater management.
