Define compressibility.

Answer»

Solution :(i) The reciprocal of the BULK modulus is called 6. compressibility. It is DEFINED as the fractional CHANGE in volume per unit increase in PRESSURE. (ii) From the equation `K = -(sigma_n)/(epsi_v) = - ((Delta P)/(DeltaV))/(V) `we can say that the compressibility
`C = 1/K = (epsi_v)/(sigma_n) = - ((Delta V)/(V))/(Delta P)` .
