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).

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
