Which of the following is false about changes in aerosol suspensions over time?
 
  a. Liquid aerosol particles can shrink (evap-oration) or grow (water absorption).
  b. The rate of particle growth is directly proportional to particle size.
  c. Small water-based particles tend to shrink when exposed to dry gas.
  d. Aerosols of water-soluble salts tend to grow in a humidified environment.

Question 2

What is the process by which aerosol suspension changes over time?
 
  a. Evaporation
  b. Deposition
  c. Aging
  d. Sublimation

Answer to Question 1

ANS: B
The relative rate of particle size change is inversely proportional to the size of a particle, so the small particles grow or shrink faster than larger particles.

Answer to Question 2

ANS: C
The process by which an aerosol suspension changes over time is called aging.
