Dear all,

I obtained this figure through water adsorption isotherm from low presure to 20 atm under 298 K. Under this temperture water should saturate when P = 3.14 kPa and change from gas phase to liquid phase. But in my result, it saturate when P = 2 atm. I don't what happened, could anyone tell me how to corrcet the result.

Thank you !!!
