Muragan,

1) What you are asking is a problem of thermodynamics. You clearly need
   to learn some thermodynamics (classical? statistical?, probably both).

2) wien 2k provides you the total energy of your system and the
   vibrational properties of your system. The total energy is basically
   the internal energy. With the vibrational properties you recover
   a big component of the temperture.

3) To resume a complex sybject: learn some thermodynamics.

Best regards,
             Dr. Víctor Luaña
