2. Calculate the initial condensation rate on a given plastic ball filled with snow and the heat transfer rate to it. The radius of the plastic snow ball is ( 0.1 mathrm{~m} ) (the plastic shell is very thin and can be neglected) and its temperature is ( 0^{circ} mathrm{C} ). Assume that the ball is exposed to an atmospheric saturated steam; and, as an initial approximation, the wet perimeter is equal to the initial diameter.

Write the detailed process.
