Question

what is the dew point?
the point at which humidity reaches 50%
the time of day when humidity is typically the highest
the temperature at which water vapor in the air condenses
the temperature at which air pressure is the highest

Explanation:

To determine the dew point, we analyze each option:

• Option 1: Dew point is not related to 50% humidity specifically.
• Option 2: Dew point is a temperature, not a time of day.
• Option 3: The dew point is defined as the temperature at which water vapor in the air condenses into liquid water (like dew), matching the scientific definition.
• Option 4: Dew point has no direct relation to air pressure's highest point.

Answer:

C. The temperature at which water vapor in the air condenses
