Problem 4: Make a plot showing the change in equilibrium vapor pressure with radius of curvature for a spherical material from 1 nm to 1 mm at 700 C. The molar volume of the material is 1.6 x 10 mand the surface energy is 0.6 J m. (Hint: the sigma term in the Young- Laplace equation can be defined as the vapor pressure of a curved surface for a given substance minus the vapor pressure of the flat surface of the same substance. Please plot the following: Peurved Pfar + (1/r, + 1/r,)* I, where gamma is the surface energy. Please use a Pala value of 1 x 104 Torr (you will likely have to adjust units on one/some of the given quantities to make this work)
