Answer 2

Calculating Absolute Humidity

To calculate the absolute humidity of the air, we can use the formula:

Absolute Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) × 100

Where: - Actual Vapor Pressure is the pressure exerted by water vapor in the air. - Saturation Vapor Pressure is the maximum pressure that water vapor can exert at a given temperature.

Finding Actual Vapor Pressure

At 25°C, the actual vapor pressure of water can be found using the Antoine equation, which gives the vapor pressure of pure substances as a function of temperature. The Antoine equation for water is:

ln(P) = A - (B / (T + C))

Where: - P is the vapor pressure in mmHg. - T is the temperature in degrees Celsius. - A, B, and C are constants specific to the substance.

Using the Antoine equation, we can calculate the actual vapor pressure of water at 25°C.

Finding Saturation Vapor Pressure

The saturation vapor pressure at 25°C can be directly obtained from reliable sources.

Calculation

Let's proceed with the calculations to find the absolute humidity of the air at 25°C and 65% relative humidity.
