Answer to Question 1

ANS: A
The boiling point of a liquid is the temperature at which its vapor pressure equals atmospheric pressure.

Answer to Question 2

ANS: A
Capillary action is the basis for blood samples obtained by use of a capillary tube. The absorbent wicks used in some gas humidifiers are also an application of this principle, as are certain types of surgical dressings.
