Question:

Can the dew point of a mixture and the bubble point of a mixture (at a composition where multiple components are present) ever be the same? Why or why not?

Dew and Bubble Points:

When a substance is in vapor liquid equilibrium, a certain fraction exists as the vapor phase and a certain fraction exists as the liquid phase. The bubble point is the point at which the first liquid molecule vaporizes into a gas and a bubble forms. The dew point is the opposite, and is the point at which the first vapor molecule condenses to form a droplet of liquid.
