Under appropriate conditions of temperature and pressure, solids and liquids tend to evaporate to a gaseous form, and gases tend to condense back. 10% of the temperature especially at high temperatures. Plot the vapor pressure of water in mm hg versus temperature in °c, including points for 2 mm hg at 0 °c and 760 mm hg at 100 °c. It is the experience of high altitude hikers that it takes. It also looks at how saturated vapour pressure varies with temperature, and the relationship between saturated vapour pressure and boiling point. Where, e = actual vapor pressure, es = saturated vapor pressure, rh = relative humidity, td = dewpoint temperature in celcius, t = temperature in celcius. We find that water at 25 c has a vapor pressure of 23.8 mm hg 5 x. Once air becomes saturated, water will condense out to form clouds, dew or films of water over leaves. The fact that the vapor pressure is equal to the external pressure can become important when talking about boiling temperatures at various altitudes.
