About Us! The Bulk Modulus Elasticity can be expressed as Temperature E = - dp / (dV / V) 0 where

E = bulk modulus elasticity dp = differential change in pressure on the object

dV = differential change in volume of the object V = initial volume of the object The Bulk Modulus Elasticity can be alternatively expressed as E = dp / (d / ) where d = differential change in density of the object = initial density of the object An increase in the pressure will decrease the volume (1). A decrease in the volume will increase the density (2). (2)
