The difference in how smell disperses depends on the speed of release and airflow dynamics. Here’s a simplified explanation:
- Slow Release (Silent): When gas is released slowly, it doesn’t mix as much with surrounding air immediately. This allows the smell to remain concentrated and linger close to the source, making it easier to notice. It also has more time to diffuse before being diluted, which intensifies the odor.
- Fast Release (Open or Loud): When gas is released quickly, it disperses rapidly and mixes with the air. This dilution reduces the intensity of the smell. Additionally, the movement of air caused by the rapid release may help carry the smell away more quickly, preventing it from lingering.
Essentially, the slower release traps the odor in a smaller, more concentrated space, while a quicker release spreads and dilutes it.
