  We study here hot nuclear matter in the quark meson coupling (QMC) model
which incorporates explicitly quark degrees of freedom, with quarks coupled to
scalar and vector mesons. The equation of state of nuclear matter including the
composite nature of the nucleons is calculated at finite temperatures. The
calculations are done taking into account the medium-dependent bag constant.
Nucleon properties at finite temperatures as calculated here are found to be
appreciably different from the value at $T=0.$
