  X-ray mosaics of the Large Magellanic Cloud (LMC) taken with the ROSAT
Position Sensitive Proportional Counter (PSPC) have revealed extensive diffuse
X-ray emission, indicative of hot >= 10^6 K gas associated with this irregular
galaxy on scales from ~10 pc to >= 1000 pc. We have selected regions of
large-scale (d >= 600 pc) diffuse X-ray emission, such as supergiant shells,
the LMC Spur, and the LMC Bar, and examined the physical conditions of the hot
gas associated with them. We find that for these objects the plasma
temperatures range from kT ~0.15 - 0.60 keV and the derived electron densities
range from n_e ~0.005 - 0.03 cm^-3. Furthermore, we have examined the fraction
of diffuse X-ray emission from the LMC and compared it to the total X-ray
emission. We find that discrete sources such as X-ray binaries and supernova
remnants (SNRs) account for ~41% and ~21% of the X-ray emission from the LMC,
respectively. In contrast, diffuse X-ray emission from the field and from
supergiant shells account for ~30% and ~6% of the total X-ray emission,
respectively.
