1. Calculate the amount of surface energy released in a coalescence of 100 m3 of fog consisting 5x10-6 m radius aqueous droplets dispersed in air into one droplet at constant temperature if the water content of the fog is 0.5 g m-3 and the surface tensions for air/water interface is 75 mN m-1 2. Estimate the average displacement of a particle diffusing on a surface of liquid in one week if the diffusion coefficient is 5x10-12 m2 s-1.
