  In this work the gravitational quantum well is used to model an effective two
level system and to perform two thermodynamic cycles, the isogravitational and
the isoenergetic ones. It is shown that the isogravitational is independent of
the scale parameter whereas the isoenergetic has a dependence on the
eigenstates chosen to form the cycle. An equivalent equation for the
isoenergetic cycle is also obtained, which is similar to the equation of state
for an isothermal process of an ideal gas. This equation reinforces the concept
of energy bath, where the temperature is replaced by the energy into the
expression of efficiency.
