Query: Masses and Thermodynamic Quantities of Quarkonia in Nonrelativistic
  Quark Model   The temperature dependent energy, mass and some of thermodynamic quantities
of charmonium and bottomonium have been calculated by solving the radial
Schr{\"{o}}dinger equation with the extended Cornell potential at finite
temperature using the Nikiforov-Uvarov method. Obtained results accord with
experimental data and theoretical results of the previous studies. We have
found the spectrum of quarkonia mass strictly decreases at high values of
temperature.
