Different systems which could exhibit size-dependent second-order phase transitions have been
studied experimentally during the last quarter century. The validity of the proposed theoretical results
is verified by comparing high-resolution experimental data with an analytical evaluation of
the heat capacity of confined 4He. It is shown that the theoretical approach to the problem of the
finite-size effect gives results that reasonably match the experimental data over a wide range of
system sizes, from tens of nanometers up to a few micrometers for the cylindrical type of confinement
geometry. The dependences of the shift of transition temperature on the cylinder size and
boundary conditions are analyzed. The agreement of the results with finite-size scaling theory is
confirmed.
