Question

1. what determines if an airborne particle is considered to be a droplet or aerosol? a size = if it is under 5μm is aerosol, larger is a droplet. b amount = if there is over 10 parts per millions of particles/air. c pathogen = when it is a contagious germ vs non - toxic particle. d testing method = using a beaker and contrast vs clia - waved test.

Explanation:

The classification of airborne particles as droplets or aerosols is mainly based on size. Aerosols are typically particles with a size under 5 micrometers (μm), while larger particles are considered droplets. The amount, pathogen - nature, and testing method are not the determining factors for this classification.

Answer:

A. Size = if it is under 5μm is aerosol, larger is a droplet.
