Document Summary
Please bring your icard and a pencil to class. The ground does not heat up instantly but rather takes time to absorb the suns energy. How it is measured: measured by barometeres, barometers use liquid mercury in a dish with a vacuum like effect. The average atmospheric pressure read by a barometer is 29. 92 inches. Vapor pressure: how many kids in a bus. Force per unit area applied only by the water vapor molecules. The pressure exerted by the water vapor measured in mb. Total air pressure is the sum of the pressures exerted by individual gases (dalton"s law) On earth, the primary contributors to the dry air pressure are o2, n2, and argon. Saturation vapor pressure: how many seat in a bus. The vapor pressure required to saturate the air (evaporation and condensation rates are equal). The temperature to which the air must be cooled for condensation to begin (forms clouds, dew, frost, and fog)
