A spherical glass bulb of 0.1 m radius is maintained at 300 K, except for an appendix with a cross-sectional area of 10-4 m2 immersed in liquid nitrogen, as shown in given Figure.
The bulb contains water vapor originally at a pressure of 13.3Pa. Assuming that every water molecule that enters the appendix condenses on the wall and stays there, find the time required for the pressure to decrease to 1.33 x 10-4 Pa.
