Questions & Step-by-Step Solutions
Which of the following factors does NOT affect the vapor pressure of a liquid?
Correct Answer: Surface area
Step 1: Understand what vapor pressure is. Vapor pressure is the pressure exerted by the vapor of a liquid when it is in equilibrium with its liquid phase.
Step 2: Identify the factors that affect vapor pressure. These include temperature, the nature of the liquid, and the presence of solutes.
Step 3: Recognize that surface area refers to how much of the liquid is exposed to air. While it can affect the rate of evaporation, it does not change the vapor pressure itself.
Step 4: Conclude that since surface area does not change the vapor pressure of a liquid, it is the factor that does NOT affect vapor pressure.
