  In this paper we study Lorentz-Violation(LV) effects on the thermodynamics
properties of a real scalar field theory due to the presence of a constant
background tensor field. In particular, we analyse and compute explicitly the
deviations of the internal energy, pressure, and entropy of the system at
thermal equilibrium due to the LV contributions. For the free massless scalar
field we obtain exact results, whereas for the massive case we perform
approximated calculations. Finally, we consider the self interacting $\phi^4$
theory, and perform perturbative expansions in the coupling constant for
obtaining relevant thermodynamics quantities.
