Volume conversion between water and steam
Thread Content
What is the volume of water vapor at standard conditions (1 atmosphere pressure, 0 degrees Celsius) equivalent to 1 cubic meter of water at 20 degrees Celsius? Or what is the volume of water vapor at 1 atmosphere and 100 degrees Celsius?

Water vapor at 1 atmosphere and 0 degrees Celsius does not exist—not that there is no vapor pressure at 0°C, but rather that the pressure cannot reach 1 atmosphere. The density of water at 20 degrees is 998.203 kg/m3. The density of water vapor at 1 atmosphere and 100 degrees Celsius is 0.60 kg/m3. 1 cubic meter of water turns into saturated steam at 100 degrees: 998.203 kg / 0.60 (kg/m3) = 1663.67 m3
