Which change increases the vapor pressure of a liquid?
A.Raising the temperature
B.Lowering the temperature
C.Increasing the container volume
D.Adding more liquid
Explanation
Core Concept
More molecules gain enough kinetic energy to escape the liquid at higher temperature, so more are in the vapor phase — vapor pressure rises.
Correct Answer
ARaising the temperature
