(b) the Clausius-Clapeyron equation and the two given data points; and (c) linear interpolation between the two given points. taking the 1st estimate to be correct, calculate the percentage error associated with the second and third estimates.
1. (relative humidity) The partial pressure of water vapor in air is usually less than the equilibrium vapor pressure (or saturation pressure) at the ambient temperature; this is why a cup of water will spontaneously evaporate. The ratio of the partial pressure of water vapor to the equilibrium vapor pressure (at the same temperature) is called the relative humidity. Saturated air, at 100% relative humidity, would be in equilibrium with a cup of liquid water. The saturation pressure depends strongly...
