Abstract The temperature dependent energy and corresponding internal pressure of the hadron are obtained by taking Fermi weighted sums over internal discrete energy levels. We find that beyond the critical temperature, the solution of the hadron radius determined from the balance relation between the internal and external pressures of the hadron disappears, which shows that the quark deconfinement transition has occured. In addition, it is shown that the heat bath plays role in delaying the deconfinement process.
