  We present the analysis of baryonic and non-baryonic matter distribution in a
sample of ten nearby clusters (0.03<z<0.09) with temperatures between 4.7 and
9.4 keV. These galaxy clusters are studied in detail using X-ray data and
global physical properties are determined. Correlations between these
quantities are analysed and compared with the results for distant clusters. We
find an interesting correlation between the extent of the intra-cluster gas
relative to the dark matter distribution. The extent of the gas relative to the
extent of the dark matter tends to be larger in less massive clusters. This
correlation might give us some hints on non-gravitational processes in
clusters. We do not see evolution in the gas mass fraction out to a redshift of
unity. Within r_{500}, the mean gas mass fraction obtained is 0.16\pm0.02
h_{50}^{-3/2}.
