What happens to the vapor pressure, boiling point, and freezing point of a liquid when a solute is dissolved in the liquid to form a solution? Multiple Choice Vapor pressure increases, boiling point decreases, and freezing point decreases. Vapor pressure decreases, boiling point decreases, and freezing point decreases. Vapor pressure decreases, boiling point increases, and freezing point decreases. Vapor pressure increases, boiling point decreases, and freezing point increases. Vapor pressure increases, boiling point increases, and freezing point increases.
