Answer 2

Relative Humidity and Air Temperature

At a temperature of -5°C and a relative humidity of 50%, the amount of water vapor in the air can be calculated using the formula for calculating absolute humidity. Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature.

The formula for calculating absolute humidity is:

Absolute Humidity (g/m³) = (Relative Humidity * Saturation Vapor Pressure at the Given Temperature) / 100

Where: - Relative Humidity is the percentage of water vapor present in the air compared to the amount needed for saturation at a specific temperature. - Saturation Vapor Pressure is the maximum vapor pressure possible at a given temperature.

Let's calculate the absolute humidity at -5°C and 50% relative humidity using the saturation vapor pressure at -5°C.

Calculation

The saturation vapor pressure at -5°C can be found using the Clausius-Clapeyron equation or from a table of saturation vapor pressure values at different temperatures.

According to the Clausius-Clapeyron equation, the saturation vapor pressure (in millibars) at a given temperature (T) in degrees Celsius is given by:

E(T) = 6.11 * 10^((7.5 * T) / (237.7 + T))

Substituting T = -5°C into the equation gives:

E(-5) = 6.11 * 10^((7.5 * (-5)) / (237.7 - 5))

Calculating E(-5) gives the saturation vapor pressure at -5°C.

Using the calculated saturation vapor pressure, the absolute humidity at -5°C and 50% relative humidity can be determined using the formula mentioned earlier.

I'll calculate the absolute humidity based on the provided information.
