The vapor pressure of water at 10 °C is 1300 Pa.
(a) Find what percentage of atmospheric pressure is this? Take atmospheric pressure to be 1.013 × 105Pa.
(b) Find what percentage of the total air pressure at 10 °C is due to water vapor when the relative humidity is100%?
(c) The vapor pressure of water at 35 °C is 5500 Pa. Determine the relative humidity at this temperature if the partial pressure of water in the air has not changed from what it was at 10 °C when the relative humidity was 100 percent?
