Question

The relative humidity (for a given volume of air), expressed as a decimal fraction, is

A) Pressure humidity
B) Specific humidity
C) Dew point
D) Mixing ratio

Answer 1

Percent relative humidity is the ratio of vapor density to saturation vapor density multiplied by 100; it's not pressure humidity, specific humidity, dew point, or mixing ratio.

Step-by-step explanation:

The relative humidity (for a given volume of air), expressed as a decimal fraction, is percent relative humidity. The percent relative humidity is defined as the ratio of vapor density to saturation vapor density.

Using the information provided, if the air contains 9.40 g/m³ of water vapor, and the saturation vapor density at a given temperature is 23.0 g/m³, the calculation for percent relative humidity would be:

percent relative humidity = (vapor density / saturation vapor density) x 100 = (9.40 / 23.0) x 100
