How can one determine the relative humidity on a particular day at a given place?

  1. A. If temperature is given
  2. B. If absolute humidity is given
  3. C. If both temperature and absolute humidity are given
  4. D. If percentage of absolute humidity is given

Correct Answer: C. If both temperature and absolute humidity are given

Explanation

Relative humidity is the ratio of absolute humidity (actual water vapor present) to the maximum moisture-holding capacity of the air, which depends directly on the ambient temperature. Therefore, both values are required.
