Answer:
Conclusion
The weight of the suspended particles in the area with heavy vehicular traffic is greater than that in the area with very little traffic. This is because the air in the areas with heavy traffic is rich in smoke, dust and particulate matter when compared to the areas with little traffic.
Precautions
The outer surface of the polythene bag containing the bundle of leaves should not have any vaseline sticking to it.
