Condensation is the process where water vapor in the air changes into liquid water. It occurs when warm, moist air cools down to its dew point - the temperature at which air becomes saturated and can no longer hold all its water vapor. This is why you often see droplets forming on cold surfaces, like windows on a chilly day, a cold drink on a hot day, or the ceiling of a humid indoor swimming pool. Condensation plays a crucial role in the water cycle, helping form clouds, fog, and dew.
