The temperature at which cooling air begins condensing is called the

• A. Dew Point
• B. Relative Humidity
• C. Photochemical Smog
• D. Blizzard

Answer: (A)

When air is cooled to the temperature at which it can no longer hold all the water vapor, condensation begins. That specific temperature is the dew point. At the dew point, the air is saturated and ready to condense water vapor into liquid droplets, forming dew on surfaces, fog, or clouds in the sky. The dew point depends on how much moisture is in the air: more moisture means a higher dew point, while drier air has a lower dew point. Relative humidity is just a percentage of how close the air is to saturation, not a temperature. Photochemical smog and blizzards describe pollution and severe weather, not the condensation temperature.
