How does the weight of chlorine gas compare to air?

  1. It is lighter than air

  2. It weighs the same as air

  3. It is 2 1/2 times heavier than air

  4. It is 3 times heavier than air

The correct answer is: It is 2 1/2 times heavier than air

Chlorine gas is significantly denser than air, specifically it is approximately 2.5 times heavier than air. This density plays a crucial role in understanding how chlorine behaves in the atmosphere and within water treatment systems. When chlorine is released, its greater weight means that it tends to remain closer to the ground rather than dispersing into the air quickly. This characteristic must be taken into consideration during chlorine handling and ventilation to ensure safety and effectiveness in its application, particularly in water treatment plants where chlorine is used for disinfection. Understanding the density comparison helps operators anticipate how chlorine will move in the environment, which is critical for preventing safety hazards related to chlorine exposure and ensuring proper treatment processes.
