Suppose you hear on the radio that the relative humidity is 90 percent on a winter day. can you conclude that this air contains more moisture than air on a summer day with a 40 percent relative humidity? explain why or why not.

Explanation:

Humidity: It is the amount of water present in the air.

Relative humidity is the ratio of the actual moisture in the air to the maximum moisture air can hold.

In the given problem,  the relative humidity is 90 percent on a winter day.  This air contains more moisture than air on a summer day with a 40 percent relative humidity.

No, we can not conclude this as it depends on the temperature. Relative humidity depends on the temperature. The warmer air can hold more water vapor than cooler air on a winter day.   It is not possible that there is 90 percent relative humidity on a winter day than the air on a summer day with a 40 percent relative humidity.
