4. The vapor pressure of water is po = 3.1698 kPa at T = 298 K. At the same temperature, the surface tension of the water-steam interface is y = 72 103 N/m. The molar volume of liquid water is V = 1.8 10-5 m/mole and it may be assumed to be constant. Calculate: (a) (10 pts.) (b) (10 pts.) the vapor pressure of a liquid drop of radius r = 2 nm = 2 10-9 m at T = 298 K. the vapor pressure of water in a cylindrical pore of radius r = 2 nm = 2 10-9 m at T = 298 K. 4.
