Water is most likely to be condensing when we observe which of the following atmospheric conditions?. A. a heavy rainstorm.
B. a very cloudy sky.
C. a clear sky.
D. a light snow.

Answers

Answer: B. a very cloudy sky

Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.

Answer: B

Condensation is a process via which a liquid directly converts to a gaseous state, skipping the liquid state altogether. Therefore, a very cloudy sky is an example of water being converted to gaseous state directly.
