Which of these changes will increase the vapor pressure of water in a sealed container?
Group of answer choices

Shake the container vigorously and let the water settle.

Increase the temperature of the water in the container.

Add more water and reseal the container

Add salt to the water and reseal the container.

Option B

Explanation:

Salt is a non-volatile solute and hence adding salt will increase the boiling point of water and hence reduce the vapor pressure. While on the other hand, adding more water will require more time to boil and hence produce vapor and thus the vapor pressure. Shaking will also not help in increasing the vapor pressure. Thus, only increasing the temperature of the water will create more vapors at a faster rate and hence increase the vapor pressure.

Thus, option B is the correct answer
