The relative humidity in a green house at 35.0°C is 88.5%.

Calculate the vapor pressure of water vapor in the greenhouse (in Pa).

Data: vapor pressure of water at 35.0°C = 41.2 mmHg (1 mmHg = 1.33 x 10^-1 kPa)

Question

The relative humidity in a green house at 35.0°C is 88.5%.

Calculate the vapor pressure of water vapor in the greenhouse (in Pa).

Accepted Answer

φ = $\frac{P_{H 2 O}}{{P^{0}}_{H 2 O}}$ x 100

P_H2O = partial pressure of the water vapor in the greenhouse P⁰_H2O = equilibrium vapor pressure of water at the same temperature

P⁰_H2O = 41.2 mmHg = 5.49 kPa P_H2O =

\frac{φ {P^{0}}_{H 2 O}}{100}

= 4.86 kPa = 4860 Pa
