A. Given that the surface energy, mass density, and molar mass of Ag are respective 1140 erg/cm2, 10.5 g/cm3, and 108 g/mol;

B. Consider spherical Ag particles of radii 3nm, 30nm, 300nm, and 3000nm;

a) Calculate molar volume of Ag at room temperature;

b) Assuming that the molar volume of Ag does not change as temperature changes, calculate the ratio of Ag vapor pressures over the spherical Ag particles to its bulk vapor pressure at 1000K.

c) What would be a characteristic particle size below which surface energy effects on vapor pressure need to be considered?
