We noticed that the required degree of superheat depends
both on the surface condition (the size of the nucleation sites) and the type
of liquid (wetting versus non-wetting). Regarding the type of liquid, we want
to examine two extreme cases. Find the required degree of superheat for
nucleation for liquids that completely wet the surface (_ = 0o).
Similarly, find the degree of superheat for completely non-wetting liquids
(_ = 180o). [Ans.: For _ = 0, there is no nucleation. For
_ = 180, no superheat is required].
