Condensation of water vapor leads to the formation of which of the following?

• A. Clouds, fog, or dew
• B. Rain
• C. Snow
• D. Hail

Answer: (A)

Condensation is the change of water vapor into liquid water when air cools to its dew point or becomes saturated. This produces visible moisture in the air, which you see as clouds aloft, fog near the ground, or dew on surfaces. These are direct results of water vapor turning into liquid. Precipitation like rain, snow, or hail happens later, after the cloud droplets or ice crystals grow large enough and the atmospheric conditions drive them to fall or partially freeze. So condensation forms clouds, fog, or dew, making that option the best choice.
