Which is a proper example of a human-made aerosol?
Answer and explanation
Correct answer: Smoke from vehicles and industries
Aerosols are tiny solid particles or liquid droplets suspended in air. Vehicle exhaust and industrial emissions release soot, ash, sulphates and other fine particles, so they are human-made aerosols. Option B is therefore correct. Sea-spray salt is a natural aerosol, pure nitrogen is a gas rather than an aerosol particle, and water vapour is a gas even though it may later condense into droplets.
