When air is cooled below the dew point?

When air is cooled below its dew point, the water vapor in the air begins to condense into liquid water, forming dew or fog. This process occurs because cooler air can hold less moisture than warmer air, leading to saturation. As a result, the excess moisture is released, often visible as droplets on surfaces or as low-lying clouds. This phenomenon is crucial in weather patterns and the water cycle.
