Water vapor that condenses on objects that have cooled below the condensation point of the air around it is known as what?

The phenomenon described in the question refers to the accumulation of water vapor that forms on surfaces when they cool below the dew point of the surrounding air. This process occurs when the temperature of an object, such as grass, leaves, or even a car windshield, falls below the temperature at which the air can hold moisture, leading to the condensation of water vapor into liquid water. This is commonly observed as droplets on cool mornings.

Dew is a common term used to describe this condensation that appears as small water droplets on surfaces. It typically occurs overnight when temperatures drop, leading to moisture in the air condensing onto surfaces. The distinction between dew and other terms is important.

Snow forms from frozen water vapor in the atmosphere and falls to the ground as solid precipitation, which does not apply to the given scenario. Frost, on the other hand, occurs when water vapor freezes onto surfaces without first turning into liquid, and usually happens below the freezing point. Humidity refers to the amount of water vapor present in the air, not the condensation that occurs on surfaces.

Thus, the term "dew" specifically captures the process described, making it the correct answer.
