Which of the following conditions indicates the release of moisture as condensation?

The release of moisture as condensation occurs when warm, moist air is cooled. This phenomenon happens because warm air has a greater capacity to hold moisture compared to cold air. When this warm, moist air is cooled, its ability to retain moisture decreases, leading to the condensation of water vapor into liquid water, which can appear as droplets on surfaces.

For instance, when warm air in a room contacts a cool surface like a window, the air near the window cools down. As it cools, it reaches its dew point, and the moisture in the air condenses to form water droplets on the glass. This is a common observation in many environments, such as during colder seasons when indoor heating creates warm, moist air that interacts with cooler surfaces.

In contrast, dry air at low temperatures does not encourage condensation because it contains very little moisture. Warm, moist air being heated may lead to an increase in temperature and comfort without resulting in condensation since the air continues to hold moisture. Cold air being heated also does not lead to condensation, as heating it reduces relative humidity, further discouraging water vapor from transitioning into liquid form.
