We find that the temperature and density imhomogeneities have nearly a universal distribution that resembles the lognormal function. With this model, we find that the inhomogeneities can explain the reported systematic bias in cluster temperature and may explain the systematic underestimate of the Hubble constant determined from the Sunyaev Zel dovich e#ect. We conclude that the inhomogeneity significantly a#ects the cosmological implications of galaxy clusters
