Among solids, liquids and gases, which posses the greatest bulk modulus?
Bulk modulus is defining the ability of a material to resist deformation in terms of volume change, under pressure.
Bulk modulus =PΔV/V
As solids have long-range order by its nature. Because the atoms of a crystal are arranged in an ordered pattern that stretches all the way across its material because of which if the same amount of pressure will be applied on solids, liquid, and gases then minimum fractional change in volume will be for solid.
Thus solids are having the greatest Bulk Modulus.
Option A is correct.
