  a. Critical temperature c. Boiling point
  b. Critical point d. Latent heat

Question 2

The point at which the vapor pressure of a liquid equals atmospheric pressure is known as which of the following?
 
  a. Critical temperature c. Boiling point
  b. Vapor pressure d. Latent heat

Answer to Question 1

ANS: A
This is the definition of critical temperature.

Answer to Question 2

ANS: C
The boiling point is the temperature at which the vapor pressure of a liquid equals atmospheric pressure. Critical temperature is the temperature above which gases cannot convert back to liquid. Critical pressure is the amount of pressure applied at the critical temperature to maintain balance between the liquid and gas phases.
