  The thermodynamic properties of loop quantum cosmology (LQC) without
considering the Lorentz term were established in \cite{Zhu09}. In this paper,
we extend this result to the recent proposed new model of LQC with the Lorentz
term. We investigate the thermodynamics of LQC on the apparent horizon of the
Friedmann-Lematre-Robertson-Walker universe. The result shows that the
effective density and effective pressure in the modified Friedmann equation of
LQC not only determines the evolution of the universe but can also serve as the
thermodynamic quantities. Moreover, with the help of the Misner-Sharp energy,
the first law of thermodynamics of the LQC is still valid as expected. This in
turn endows precise physical meaning to the effective matter density
$\rho_{eff}$ and the effective pressure $P_{eff}$.
