Questions & Step-by-Step Solutions
What is the term for the pressure exerted by a vapor in equilibrium with its liquid?
Correct Answer: Vapor pressure
Step 1: Understand that a liquid can turn into a vapor (gas) when it is heated or when it evaporates.
Step 2: Recognize that when a liquid and its vapor are in a closed container, they can reach a state where the amount of liquid turning into vapor equals the amount of vapor turning back into liquid.
Step 3: This state is called 'equilibrium' because the processes are balanced.
Step 4: The pressure that the vapor exerts at this equilibrium state is what we call 'vapor pressure.'
Step 5: Therefore, the term for the pressure exerted by a vapor in equilibrium with its liquid is 'vapor pressure.'
