How does atmospheric pressure not affect vapor pressure? Yet if you lower the atmospheric pressure the...
The _____ pressure of the water vapor in atmospheric air is called vapor pressure.
if the atmospheric pressure lowers what affect does it have on the boiling point
(a) What is the vapor pressure of water at 20.0◦C? (b) What percentage of atmospheric pressure does this correspond to? (c) What percent of 20.0◦C air is water vapor if it has 100% relative humidity? (The density of dry air at 20.0◦C is 1.20 kg/m3). I got that the vapor pressure of the water will be 2.33x103 Pa, but I am getting hung up on the formula for part b, which is where I can really use the extra help...

5) If you had measured the vapor pressure of the tert-butanol solution that you prepared in the lab, would you have expected the vapor pressure to be: a) Elevated b) Lowered c) Stay the same
II Revi Part A The vapor pressure of a substance describes how readily molecules at the surface of the substance enter the gaseous phase. At the boiling point of a liquid, the liquid's vapor pressure is equal to or greater than the atmospheric pressure exerted on the surface of the liquid. Since the atmospheric pressure at higher elevations is lower than at sea level, the boiling point of water decreases as the elevation increases. The atmospheric pressure at sea level...
