Answer to Question 1

ANS: B
As the temperature increases, the drug concentration increases, as does the likelihood of unde-sired side effects.

Answer to Question 2

ANS: B
The exit velocity of the aerosol is low, less than 4 m/sec, and the particle size can range between 2 and 3 m MMAD, varying with the exit diameter of the apertures (Figure 39-27).
