Calculating pressure volume work
WebWork, \(w\), may come in different forms, but it too can be measured. One important form of work for chemistry is pressure-volume work done by an expanding gas. At a constant external pressure (for example, … WebIn various units, the value of 1 atm pressure are given by, 1 atm = 760 mm of Hg = 101325 N/m 2 = 1.01325 bar. = 10.33 m of H 2 0 = 1.033 kg/cm 2. Another useful unit of pressure is 1 Torr and this is equal to pressure exerted due to 1 mm of Hg = 133.34 N/m 2. Pressure is measured by using-. 1.
