Microgels suspended in liquid are found to be swollen significantly from their original radius. The microgel particle interacts through soft sphere repulsive interparticle potential 1/rⁿ where n determines the hardness of interparticle potential. In present work the elastic response of soft colloids are studied. The ratio of high-frequency bulk modulus (K_∞) and shear modulus (G_∞) increases with volume fraction. The change of K_∞/G_∞ or poison's ratio (ν) with their packing fraction is also discussed here. The equation of state describes relation between compressibility factor (Z) and the volume fraction (η) of soft microgel suspended in a liquid at constant temperature. The dynamics of relaxation of glass forming liquid is determined by a quantity called fragility. There is an apparent correlation between fragility (m) and the hardness of interparticle potential (n). In particular I focus on how m changes with n. A simple relationship between the low volume fraction activation energy of relaxation and the hardness of interparticle potential is determined from the low volume fraction estimation of fragility (m). The correlation between K_∞/G_∞ with (1/n) is also reported here.
