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 \geq 10 ^ { 6 } K gas associated with this irregular galaxy on scales from \sim 10 pc to \geq 1000 pc .
We have selected regions of large-scale ( d \geq 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 \sim 0.15 - 0.60 keV and the derived electron densities range from n _ { e } \sim 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 \sim 41 \% and \sim 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 \sim 30 \% and \sim 6 \% of the total X-ray emission , respectively .
