What happens to chlorine leaks in metal containers over time?

Chlorine leaks in metal containers tend to become larger over time due to the corrosive nature of chlorine gas. When chlorine is stored in metal containers, it can react with the metal, leading to corrosion. This process not only creates pinholes or cracks but can also compromise the structural integrity of the container itself. As corrosion progresses, it can increase the size of these openings, resulting in larger leaks.

The other options suggest scenarios where the leaks would either diminish or stabilize, which does not align with the reality of chlorine's effects on metal. In fact, rather than reducing in size, leaks are likely to worsen if the container is not properly managed or replaced, highlighting the importance of regular inspections and maintenance of chemical storage systems.
