A gas mixture contains 10 mol% water (H2O) and 90 mol% nitrogen (N2). Take as a starting point in both sub-questions that the gas mixture at the start has the temperature 50C and the pressure 1 atm (760 mmHg). Assume that the gas mixture behaves as an ideal one gas. The density of water in the liquid phase is 1000 kg/m3 . a) The gas mixture is cooled at constant pressure. At what temperature are the first formed the water drops? b) A container of 30 liters is filled with the gas mixture and then closed. The container cooled until all the water has condensed. What volume will the condensed water have have?
