Answer 2

Partial Pressure of Water Vapor and Air Temperature

The partial pressure of water vapor is given as 2.07 kPa. We are asked to determine the air temperature when the relative humidity is 100%.

To find the air temperature, we can use the relationship between partial pressure, temperature, and relative humidity. The formula is as follows:

Pv = (RH/100) * Psat(T)

Where: - Pv is the partial pressure of water vapor - RH is the relative humidity - Psat(T) is the saturation vapor pressure at temperature T

In this case, the relative humidity is 100%, which means the air is saturated with water vapor. Therefore, the partial pressure of water vapor is equal to the saturation vapor pressure at the given temperature.

Let's find the temperature using the given partial pressure of water vapor.

According to source the formula for finding the temperature when the relative humidity is 100% is:

t = 100 - (Pv / 2.2)

Substituting the given partial pressure of water vapor (2.07 kPa) into the formula, we can find the air temperature.

t = 100 - (2.07 / 2.2)

Calculating this, we find that the air temperature is approximately 99.41°C.

Please note that this calculation assumes standard atmospheric conditions and may not be accurate in all situations.
