Answer to Question 1

ANS: D
Aerosols have the potential to cause both local and systemic effects. However, these effects largely depend on the drug concentration delivered, particle size, temperature, and volume of the aerosol.

Answer to Question 2

ANS: C
Water vapor exerts a pressure (PH2O) that results from the continuous, random movement of water molecules. It is not a true gas and does not have a constant pressure. As the temperature of a gas increases, water vapor pressure increases and water molecules leave the liquid state through evaporation.
