When droplets are smaller, they are more likely to:

Smaller droplets are more likely to remain airborne due to their reduced weight and increased surface area relative to their volume. When droplets are tiny, they are less affected by gravitational forces, allowing them to float and travel longer distances in the air. This property is particularly significant in applications such as pest control or aerosol delivery, where it’s essential for the particles to remain suspended longer to ensure that they reach their intended targets effectively.

In contrast, larger droplets have a greater tendency to fall to the ground quickly due to gravity, making them less effective for applications that rely on airborne distribution. Additionally, smaller droplets evaporate less quickly than larger ones, as they have a larger surface area relative to their volume, which helps them maintain their substance longer under certain conditions. While they can aggregate into larger droplets, this process is generally more pertinent to specific conditions and does not primarily define the behavior of smaller droplets in the airborne context.
