  We deduce the relation between the critical temperature associated to the
symmetry breaking of scalar fields with one--loop correction potential immersed
in a thermal bath and the condensation temperature of the aforementioned
system, assuming a harmonic oscillator type potential. We show that these two
temperatures are related through the \emph{scale} associated to the system. In
this aim, we infer the order of magnitude for the \emph{scale} as a function of
the corresponding healing length, in order to give a criterium to compare both
temperatures. Additionally, we prove that the condensation temperature is
independent of the thermal bath within the semiclassical approximation, for a
positive coupling constant, assuming that the thermal bath contribution is the
lowest energy associated to the system.
