Chapter 13, Problem 76A

Interpretation Introduction

Interpretation: It is to be explained if relative humidity can be exceeded by $100\%$ or not.

Concept introduction:

The amount of water vapor in the air is known as humidity. The gaseous form of water, known as water vapor, is typically undetectable to the naked eye.

Answer to Problem 76A

Relative humidity can be exceeded by $100\%$ .

Explanation of Solution

The system's temperature and pressure affect humidity. Relative humidity, which is sometimes stated as a percentage, compares the current level of absolute humidity to the highest humidity possible under the same temperature conditions.

Ordinarily, relative humidity is reported as a percentage; a larger percentage denotes a higher relative humidity of the air-water mixture. The dew point is reached when the air is saturated and has a relative humidity of 100%.

The relative humidity can approach 100% in the absence of an outside body on which droplets or crystals can form. In this case, the air is referred to be supersaturated.
