A simple theory is proposed to predict the effect of pressure for study of volume expansion of nanomaterials. Different possible forms of equation of state are discussed with their correlations. Only two input parameters, namely, the bulk modulus and its first pressure derivative, are required for calculations. We have considered a wide variety of nanomaterials, such as, CdSe (4.2 nm), Fe-Cu (14 nm), ƴ-Al 2 O 3 (67 nm), ƴ-Al 2 O 3 (37 nm), Ni (20 nm), Fe (10 nm), CeO 2 (cubic Fluorite phase)
