If air is cooled to its dew point, what happens to water vapor?

Cooling air to its dew point means the air has become saturated with water vapor. At that temperature, the air can no longer hold all the vapor, so the excess vapor condenses into liquid water. This condensation forms droplets as dew on surfaces, fog, or clouds. So the water vapor decreases by changing into liquid rather than increasing, and the air doesn’t become drier or experience a rise in temperature.
