Steam condensation question

  1. May 17, 2017 #1
    What I want to be clarified in this thread is about condensation of steam at constant pressure. Suppose Suppose an enclosed volume of size 1 m³ and it's filled with steam at 100°C and 1 barA pressure. Now, the container is connected to a chamber filled with dry air in such a way that the pressure inside the chamber can't change. Now, the temperature has been lowered to 70°C. Question is, what % of steam will be condensed then.
    At 100°C, the pressure of steam is 101.32 kPa while at 70°C it's 31.15 kPa. Does that mean that {1-(31.15/101.32)}% of steam i.e. approx 59.256% of steam has been converted to water?
